Add LICENSE

[serisman]

This repo need a clearly identified LICENSE so people know what can and cannot be done with it.

@freepdk, my preference for this is MIT, but these files have their roots from easy-pdk-programmer-software (even though they have been changed dramatically from what was/is there) which is GPL v3. Are you ok with (re-)licensing these include files as MIT?

Pull Request to add Copyright and License information: #6

SDCC suggested GPL + LinkExcpetion. LGPL is a bit different.

Yeah, I couldn't really find that as an 'official' license. Do you have a link that shows that as being a real thing?

I couldn't find it on http://www.gnu.org/licenses, and it isn't directly listed on their exceptions page either: https://www.gnu.org/licenses/exceptions.html

GitHub doesn't know about it: https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/licensing-a-repository

SPDX doesn't directly list it (unless it is one of the deprecated ones): https://spdx.org/licenses/

Wikipedia isn't really all that clear, although they do list LGPL as being related: https://en.wikipedia.org/wiki/GPL_linking_exception

Or, do we just list this as GPL 2.0 and include our own exception text (similar to what SDCC uses)? That feels a bit dirty to not use an 'official' license, but maybe it is ok?

Ok, here is a different PR with GPL v2 with Linking Exception: #7
