feat: added nestJsTimestampTypeWrapper (#567)

* feat: added nestJsTimestampTypeWrapper

* fix: wrappers import

* feat(integration): added nestjs-simple-usedate

* fix: genfiles changes

* revert: protobufjs now fixed on 6.8.8

* update integrations

* improve codegen check for ProtobufTimestampWrapper

* fix lint and rename test

* add additional test

* excluded 2 tests thats failed in CI

+/**
+ * A Timestamp represents a point in time independent of any time zone or local
+ * calendar, encoded as a count of seconds and fractions of seconds at
+ * nanosecond resolution. The count is relative to an epoch at UTC midnight on
+ * January 1, 1970, in the proleptic Gregorian calendar which extends the
+ * Gregorian calendar backwards to year one.
+ *
+ * All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+ * second table is needed for interpretation, using a [24-hour linear
+ * smear](https://developers.google.com/time/smear).
+ *
+ * The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+ * restricting to that range, we ensure that we can convert to and from [RFC
+ * 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+ *
+ * # Examples
+ *
+ * Example 1: Compute Timestamp from POSIX `time()`.
+ *
+ *     Timestamp timestamp;
+ *     timestamp.set_seconds(time(NULL));
+ *     timestamp.set_nanos(0);
+ *
+ * Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+ *
+ *     struct timeval tv;
+ *     gettimeofday(&tv, NULL);
+ *
+ *     Timestamp timestamp;
+ *     timestamp.set_seconds(tv.tv_sec);
+ *     timestamp.set_nanos(tv.tv_usec * 1000);
+ *
+ * Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+ *
+ *     FILETIME ft;
+ *     GetSystemTimeAsFileTime(&ft);
+ *     UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+ *
+ *     // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+ *     // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+ *     Timestamp timestamp;
+ *     timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+ *     timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+ *
+ * Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+ *
+ *     long millis = System.currentTimeMillis();
+ *
+ *     Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+ *         .setNanos((int) ((millis % 1000) * 1000000)).build();
+ *
+ *
+ * Example 5: Compute Timestamp from Java `Instant.now()`.
+ *
+ *     Instant now = Instant.now();
+ *
+ *     Timestamp timestamp =
+ *         Timestamp.newBuilder().setSeconds(now.getEpochSecond())
+ *             .setNanos(now.getNano()).build();
+ *
+ *
+ * Example 6: Compute Timestamp from current time in Python.
+ *
+ *     timestamp = Timestamp()
+ *     timestamp.GetCurrentTime()
+ *
+ * # JSON Mapping
+ *
+ * In JSON format, the Timestamp type is encoded as a string in the
+ * [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+ * format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+ * where {year} is always expressed using four digits while {month}, {day},
+ * {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+ * seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+ * are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+ * is required. A proto3 JSON serializer should always use UTC (as indicated by
+ * "Z") when printing the Timestamp type and a proto3 JSON parser should be
+ * able to accept both UTC and other timezones (as indicated by an offset).
+ *
+ * For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+ * 01:30 UTC on January 15, 2017.
+ *
+ * In JavaScript, one can convert a Date object to this format using the
+ * standard
+ * [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+ * method. In Python, a standard `datetime.datetime` object can be converted
+ * to this format using
+ * [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+ * the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+ * the Joda Time's [`ISODateTimeFormat.dateTime()`](
+ * http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
+ * ) to obtain a formatter capable of generating timestamps in this format.
