How yorkie-js-sdk works

yorkie-js-sdk uses gRPC-web for communicating with Yorkie agent built on gRPC.

 +--Browser--+           +--Envoy---------+         +--Yorkie-----+
 |           |           |                |         |             |
 | gRPC-web  <- HTTP1.1 -> gRPC-web proxy <- HTTP2 -> gRPC server |
 |           |           |                |         |             |
