is there any way can keep the fieldname not change to camel-case?

hi ,I try to use protoc-gen-grpc-web to build typescript types from proto file. it work well except the fieldname be changed to camel-case.

I fork this Repository and modify the `CamelCaseJSFieldName` function. then I make & make install on my macbook,it work fine.

but I'm poor on C++,i can not build a linux version to use in linux system like the [release flie](https://github.com/grpc/grpc-web/releases).

question is :

1. can the plugin provide a option that do not change the fieldname to camel-case?
2. how to cross-compile a linux version plugin on my mac-os?

Hope helps, thx
