[Feature] CustomRP config compatibility

[IQBE]

Is your feature request related to a problem? Please describe.
As a user I would like the application to be a drop-in replacement for CustomRP.

Describe the solution you'd like
I would like to import/convert my existing CustomRP configuration file. I would also like to be able to convert my Genzai config to CustomRP.

Describe alternatives you've considered
Only way for this to be possible is by making a converter between the file types.

Additional context
CustomRP uses an XML format to store its configuration files. Converting should be as easy as just running a function that maps the xml values to the json format we're using.

I agree, I'll patch out the json in favor for the xml format. I see no rush for this so you could definitely open a pr any time soon. Goodluck!
