Better handling of inversion on B450M Mortar

[chintal]

23, #79 suggest the colors on the B450M Mortar are inverted.

Indeed, using -ir -ib -ig does produce the expected output. Specifically, inverting the state of -ir, -ib, -ig from the examples generates more or less the demonstrated output. It would be nice if this inversion could be auto detected based on motherboard id. A lot of work, I know, but is a pretty big leap if you're a new user.

Additionally, there might be some corner cases in the actual inversion due to which it is not exactly correct. When compared to the example images, I notice the following notable differences :

• Heartbeat doesn't seem to do anything at all
• Police has long (2 seconds or so maybe) gaps between the blue and red. It follows a sequence of blue - blue - red - red
• Hue wheel has the LEDs off for significant periods, maybe about 60% on 40% off

Could there be other non-color bits n the registers which are not exactly inverted which are causing this variation?

Most likely what is happening here is that the bitfields are incompatible between motherboards even with the same chipset.
