Version 2.0.8

fixes nanomsg#152 examples/websocket documentation update

Substantial transport fixes, including huge test suite overhaul.

This includes a mock for socket operations, and achieves a high level
of coverage for the most important transports.  As part of this, we
have found and fixed a number of bugs across the transport layer.

Note that tuning for KeepAlive and NoDelay has been altered -- all
sockets are now forcibly NoDelay.  Additionally, KeepAlive semantics
more closely match the modern Go net package.

Bump websocket to v1.4.1 (security fix)

Use GitHub actions for CI/CD. (nanomsg#122)

This uses GitHub actions and their own infrastructure to test macOS, Windows, and Linux.

Detect stale ipc and remove if unused
