Browserstack tests (#68)

* e2e test app

* instrumented video encode decode test

* browserstack in github actions

* fix yaml

* more action fixes

* more yml fixes

* test more codecs and control tests

* Optimize test some more

* fix supported codecs logging

* don't try simulcast encodings if using default

* clean as a part of build process

* Directly test if VP8/H264 is available for device
