Add argument for path to pico_configs file

[CodePurble]

The path to pico_configs.tsv is hard-coded in the generator script. It complains when I use the generator in other scripts and even when I symlinked the script to my PATH for convenience. An option to specify where to find it will remove all this hassle. This PR aims to do just that.

#26 is related. Maybe just that PR is enough to fix this. There's not much progress there, so I am leaving this PR as it is for now.

pico_configs.tsv will probably update more frequently than pico_project.py (the former is generated from pico-sdk), so it's probably worth including this command-line-arg regardless of #26 👍

Something has gone a bit pear shaped in that commit. Might be worth trying a "git pull --rebase" from the upstream master, then doing a push of the resulting tree to your codebase. That SHOULD update the PR to only have your changes in it. Or not...

More specifically, I think the following sequence of commands should sort you out:

git fetch origin
git checkout config-file-arg
git rebase origin/master
git push -f fork config-file-arg

This does the job. Thanks for the help!
