Creates cfg files for optimum crt-pi shader appearence. Works only for lr-fbalpha (FBA 0.2.97.39), lr-mame2003 (MAME 0.78) and consoles (currently only Nestopia/NES).

Params are:

• core (currently, mame2003, fbalpha or consoles)
• screen width (eg 1920)
• screen height (eg 1080)

Example usage: Clone into a directory, and then navigate to that directory in your command prompt, and then:

python crt_pi_configs.py mame2003 1920 1080

It will generate the cfgs and zip files containing the same in the root.

Requires Python 3.5.2 or higher (or at least, it doesn't work properly on 2.7)
