Supporting "depscheck ./..."

I'd love to see a support for doing the stats recursively on all the sub packages of a certain package excluding the vendor directory.
Thanks.

Good point. Definitely should be added.

In case it's helpful to see a snippet of how to convert packages command-line arguments into a list of full import paths (i.e., all relative import paths converted to full), feel free to look at (and take anything from) how I did it in goimporters:
