grpc -> grpcjs

notes:
 * grpcjs doesnt like ByteBuffer, i added src/bytebuffer_replacement.ts
   to have fake ByteBuffer methods that produce native nodejs `Buffer`s
 * grpcjs doesnt like calls without an argument
   (src/grpc/subscribe.ts:24)
 * grpcjs converts uint64 in a map key (map<uint64, ...>) to some hash,
   this is fixed with protobuf_long.patch which is applied after `npm i`
   protobufjs/protobuf.js#1669
