Use spdx3-validate as a library

@JPEWdev
Currently spdx3-validate can be used as a command-line tool.

Is there a way to use it as a library in a Python program?

Ya, its probably pretty easy to refactor the main into a library function

Thank you @JPEWdev
Would you have time to do it?

Hi Joshua,
I have created #9 to allow use as a library.
You now have a function spdx3validate()

Can you please check if that makes sense?
