Generate LICENSE File

[jmwright]

Some sites like GitHub expect there to be a LICENSE file present, and if it's not they assume a license hasn't been chosen. sliderule-cli may need to find a way to properly generate some sort of license file to keep those services happy. Alternatively, users will have to select a license for the repository when they create it. The drawback of doing this is that some services don't understand OWHW/FOSS dual-licensing schemes.

Should this be for the source license or documentation license?

@capsulecorplab It's been a few years and so I can't remember anymore, and this CLI got a little bit ahead of the DOF definition and the Sliderule specification which doesn't help. @m30-jrs has the master plan I think. If this Rust CLI and it's underlying library still factor into Mach 30's plans, we should get them transferred to the Mach 30 GitHub org so they can take them over.
