Support for `optional` in proto3

See original GitHub issue

Calling protoc with --experimental_allow_proto3_optional returns

filename.proto is a proto3 file that contains optional fields, but code generator protoc-gen-ts hasn’t been updated to support optional fields in proto3. Please ask the owner of this code generator to support proto3 optional.

For more information on implementation, see: https://github.com/protocolbuffers/protobuf/blob/master/docs/implementing_proto3_presence.md
