cli: how to generate static code only for necessary types?

How to generate static code only for necessary types from big definitions?

Current version generates static code for all types defined in protocol.proto:

pbjs --es6 --wrap=es6 --target=static-module --out=lib/protocol.js protocol.proto

I'd like to have an option like --types=Transaction,Contract to generate static code only for Transaction and Contract types.

Motivation: reduce javascript bundle size.

There's a --sparse option which will only generate the protos defined/used in protocol.proto. So if you split things up so that all your js-needed protos were referenced in some file, you could use that as the input. The --sparse option has some issues with nested types sometimes, but there's a PR here https://github.com/protobufjs/protobuf.js/pull/1528 which address them.

I found a solution, Eventually I cut myfile from 100,000 lines to 10,000. and i think it's more easy to use than --sparse.

Nice job, I have been waiting this feature for 6 months.
