Release v0.6.1

I added a few Module-centric hooks:

• go-build-mod
• go-test-mod
• go-vet-mod
• golangci-lint-mod
• golangci-lint-mod-fix

These hooks will walk up the path of each staged file, looking for a go.mod file. The directory containing the go.mod file will be considered a "module-root"

The command (build, test, vet...) will be executed with each module-root being the target.
