Importer doesn't accept dates before 1677 or after 2262

[dadokkio]

Describe the bug
Not sure if this is a real bug but I want to report this in any case.

If the data you want to import has a date before 1677 [in our case some windows log that default to 1601-01-01T00:00:00Z] or after 2262 the importer with pandas support will fail with:

ERROR:timesketch_importer.importer:Unable to change datetime, is it badly formed?
Traceback (most recent call last):
  File "/envs/mte/lib/python3.9/site-packages/pandas/core/arrays/datetimes.py", line 2085, in objects_to_datetime64ns

  File "pandas/_libs/tslibs/conversion.pyx", line 350, in pandas._libs.tslibs.conversion.datetime_to_datetime64
TypeError: Unrecognized value type: <class 'str'>

During handling of the above exception, another exception occurred:

It seems that valid range are:

>> pd.Timestamp.min
Timestamp('1677-09-22 00:12:43.145225')
>> pd.Timestamp.max
Timestamp('2262-04-11 23:47:16.854775807')

Expected behavior
Default the line to oldest supported value or skip the line with a warning

Used lib for import
timesketch-api-client==20210205
timesketch-import-client==20210215

I opt for skipping with a warning,

[kiddinn]

also take into consideration #1534, since that will also change ingestion of data...

and since that will use the pandas library for ingestion, it may have similar effects when the web UI is used to import the data (since pandas is already used in the importer, which is the reason for this)

[kiddinn]

so to be fair, it's not a bug per se, as in these are clearly invalid dates, it's just that we need TS ingestion to handle that in a more graceful way, so that the ingestion can still take place, and perhaps these bad dates either filtered out or time set to zero in order for the ingestion to be able to be completed.

Now #1534 has been merged in, this becomes even more important to fix.

@kiddinn are you planning to work on this bug? Otherwise I opt to free it up and someone else look into it maybe.
