Allow HTTP compression

[tovbinm]

Based on our investigation faundadb-jvm client does not use any compression by default:

faunadb-jvm/faunadb-common/src/main/java/com/faunadb/common/Connection.java

Line 393 in 61b3ddd

request.headers().set(HttpHeaderNames.CONTENT_TYPE, "application/json; charset=utf-8");

Netty supports a bunch of compression codecs, including gzip and deflate - https://netty.io/4.1/api/io/netty/handler/codec/compression/package-summary.html

It would be a great addition to allow enabling compression codec on the client side.

Thank you very much for this suggestion. We have it ticketed internally as DRV-532 and are looking into it.
