Support for other Licors

[roaldarbol]

Hi there! I'm working with a Li-7000, and figured there would be some good libraries out there. This seems to be the nicest Licor Python library, so I wondered if you'd accept pull requests if I can find way to make the library a bit more generic - maybe creating a list of supported Licors and their column names, and then you can specify which machine you have when you create the object? I appreciate it's an old library and that you may not be developing on it anymore, but thought it would be nicer to build on something already existing rather than just fork and make something new. :-)
Cheers, Mikkel
