Use PostgresNIO's default JSON coders (#195)

* Use postgres-nio's `_defaultJSONEncoder` and `_defaultJSONDecoder` global variables as the default values for the JSON coders in `PostgresDataEncoder` and `PostgresDataDecoder` * Deprecate the previous "jsonDecoder" variable of PostgresDataDecoder and rename it to "json" * Fix spacing slightly in PostgresDataDecoder * Fix spacing in PostgresDataDecoder
