tscert

This is a stripped down version of the tailscale.com/client/tailscale Go package but with minimal dependencies and supporting older versions of Go.

It's meant for use by Caddy, so they don't need to depend on Go 1.17 yet. Also, it has the nice side effect of not polluting their go.sum file because tailscale.com is a somewhat large module.
