Fix red inversion regardless of reset pin value #59

Fixes #52. This fixes a weird error where when the reset pin is passed as anything other than -1, the colors invert.

ermm this seems like a bandaid patch for an issue we haven't determined - it doesn't "make sense" - could be we are not really resetting or something?

Fair enough. I'll dive in a bit deeper tomorrow.

Ok, it had a missing init code (which I found in the IL91874 display file). After adding it in and getting the buffer bites correct, it works just fine regardless of the reset pin value.
