Several pbjson options are missing

[torkelrogstad]

The protoc-gen-prost-serde documentation states the following: This tool supports all the same options from pbjson-build.

This is not correct. One example is ignore_unknown_fields, there could be more as well. The options in pbjson-build can be found here.

The code that sets these options can be found here:

protoc-gen-prost/protoc-gen-prost-serde/src/lib.rs
