Allow PADEMU (DS3/DS4) Controller Support with CheatDevice

[browntownington]

Is your feature request related to a problem? Please describe.
For everyone that uses PADEMU with OPL and have ditched their wired controllers.. Would be great if there was an option in the ".ini" file enable PADEMU support... This way we wouldnt need to swap controllers etc if wish to use CheatDevice.

Describe the solution you'd like
I imagine it's pretty easy to implement. There are POPSTART IRX files which may work. Otherwise there is some sample code for using the DS3/DS4 controllers.

Describe alternatives you've considered
There is no alternative except keeping a wired controller plugged into port one and having to get up and swap controllers just to use cheatdevice.

Additional context
Thank you for making a great open cheat device :)
