Missing non-dependent browser integration test for botframework-streaming

[stevengum]

Describe the bug

botframework-streaming should have its own browser integration tests that are not reliant on any dependent libraries (e.g. botframework-directlinejs, botframework-webchat) or dependent's tool chains.

Expected behavior

• [ ] browser-based app using botframework-streaming should build
  • [ ] without/with the use of browserify, parcel, rollup, webpack
• [ ] no runtime errors in app from botframework-streaming

tool	test exists?
nothing	❌
browserify	❌
parcel	❌
rollup	❌
webpack	❌

With the current CI configuration and streaming E2E test, this is no longer a P0 and has been placed on the backlog for now.
