git submodule initial clone status

[wandadars]

add a feature to display information about initial submodule repo clones that might take a long time to fully clone.

One of the git repos in the ext/ is a very large initial clone when using the dependency build script. Added some coding to notify that the script hasn't frozen and is just cloning the repo, and periodically updates the user of this.

Hey Chris, a better option would be to update the build script to perform a shallow clone with git submodule update --init --recursive --depth 1. Or, better still, update the configuration to use a shallow clone by default for the given submodule(s) with git config -f .gitmodules submodule.<name>.shallow true.

Thanks @TimothyEDawson . That definitely sounds more efficient. I can't recall off the top of my head, but one of those repos takes like 5 minutes to download with the full clone 😅.
