Support customizing the methods included in messages in CLI

[jiaojiaodubai]

I am writing a browser extension script to parse the data returned the server.

In my application scenario, for those returned masses, I only need to use decode and toObject, but the current command line does not support selecting the required methods. In order to minimize the script size, I have to manually delete those redundant methods.

I would like to have some thing like:

pbjs -t static -toolsets=decode,toObject -o compiled.js file1.proto

The static target already supports this through per-method opt-out flags — each generated method group has a --no-* gate (documented in the pbjs CLI README). For keeping only decode and toObject:

pbjs -t static --no-create --no-encode --no-verify --no-delimited --no-typeurl --no-service -o compiled.js file1.proto

decode stays because it isn't disabled; toObject comes with the convert group (toObject and fromObject travel together — --no-convert would remove both). No manual deletion needed.
