cache-go

Github Action to restore and save cached Go module and build files as efficiently as possible.

Module and build files are cached separately to avoid not restoring cached build files because dependencies were changed. Likewise a Go version upgrade should not invalidate cached module files as they aren't dependent on a specific Go version. Cache restore keys are used to ensure a cache will be loaded whenever possible.
