Provide AvroRecordCodec implementations for JTS geometry types

[CloudNiner]

We have a few codecs in https://github.com/locationtech/geotrellis/tree/master/store/src/main/scala/geotrellis/store/avro/codecs for things like Extent, but not for the geometry types.

Something like https://github.com/sksamuel/avro4s might make it easier to write and maintain these?

@CloudNiner I think in our case avro4s will still require to write custom codecs manually https://github.com/sksamuel/avro4s#custom-type-mappings We have complex types and lot's of them are not case classes. Also mb it makes no sense to include codecs we don't use explicitly in the library code? Anything else (like JTS types) is a user-defined code in my opinion, I see no ways how GeoTrellis can use it to persist layers.

But we could have some separate library with JTS Avro codecs / etc.

Btw this is a perfect issue for the geotrellis-contrib repo.

Ooo great point. Closing this and opened geotrellis/geotrellis-contrib#241
