fix: treat period as a delimiter in names (#546). Thanks @alexifm!

If a model was named protoname.v1.MessageName (as if generated from `protoc`), the processed name would be Protonamev1MessageName and the model filename would be protonamev_1_message_name.py. With the change, it's ProtonameV1MessageName and protoname_v1_message_name.py, respectively.

BREAKING CHANGE: Model names generated from OpenAPI names with periods (`.`) in them will be different.
