protoc-ts-interfaces v0.0.16

• generate ts interfaces via protoc plugin
• reuses parts of https://github.com/improbable-eng/ts-protoc-gen
• JSON.stringify of the ts object results in json that is deserializable by other proto libraries

dev setup:

• install bazel
• build prep: bazel run @nodejs//:npm install
  • this is a wart, replace with fully-hermetic npm management once that matures in rules_nodejs
• to build: bazel build //...
  • the first run will take a while, mainly because protoc must be built from source
  • this includes usage of the plugin to gen d.ts's for the various scenarios in the scenarios directory
• to run tests: bazel test //...
• followed http://blog.npmjs.org/post/118810260230/building-a-simple-command-line-tool-with-npm to make the cli and publish the package to the npm repo

TODO (known):

• maps, per https://developers.google.com/protocol-buffers/docs/proto3#json
• bytes / b64
• timestamp
• duration
• might want to make enum vs const enum configurable
