Fixes #1056

As discussed with @kzantow

This checks in $GOPATH/pkg/ for a package@version, and, if it finds it, reads the licenses from there. If not found, it falls back to reading the package from the internet via the official go proxy https://proxy.golang.org

In addition, it has two new CLI flags: go-fetch bool and --go-proxy string. The fetch is supposed to enable fetching over the Internet, default to false; the proxy is supposed to override the default.

The CLI flags are not wired up, as I could not quite figure out how to pass them all the way through to the go cataloger. I managed to get them onto the app *config.Application, but there is a bunch of steps down. Some pointers would be helpful.

I do not understand why the CLI tests fail. 🤷‍♂️

At the request of @kzantow , I am splitting this one up into 2 PRs.

The first #1645 , only checks local GOPATH/mod for packages to find licenses. After that one is in, we will open a second PR, adding a CLI option to reach out to the Internet if a package is not found locally.

I rebased this on main after #1645 merged in. This needs the option added to enable finding modules on the Internet, but should be useful as a basis.

Actually, I mostly managed to get it in place. Still needs some help.
