Syntax error on WebsocketFeed

[jklappenbach]

this.objectMapper = objectMapper(new JavaTimeModule());

should probably be:

this.objectMapper = objectMapper.registerModule(new JavaTimeModule());

Otherwise, I get the following error when executing build tasks:

.../gdax-java/src/main/java/com/coinbase/exchange/api/websocketfeed/WebsocketFeed.java:58: error: cannot find symbol
this.objectMapper = objectMapper(new JavaTimeModule());
^
symbol: method objectMapper(JavaTimeModule)
location: class WebsocketFeed

It looks like the JVM version isn't specified as a source/target build in the gradle file. This would cause an issue if your project isn't set to Java 11. I will take a look at this.

Apparently I was looking at the wrong issue as I was having issues compiling as well. I've made the corrections in my branch which it should be merged into master soon
