Change bidsschematools CLI from click to argh

Your idea

@TheChymera would prefer to use argh over click. I have no opinion except that I don't want to do it myself.

I typically just use argparse, but I don't have an issue with using argh- I've never used it but I'm sure it's a good tool.

except that the last commit seems to be from ... 2016?
