Fixes#648
## Description of change
Deal with devices in hybrid packet mode that send garbage data in second
packet when it's out of bounds (outside the number of contact points).
MSDN says they're supposed to be (0, 0), but some devices don't follow
the spec.
## Testing
I don't have a device that reports garbage values but this should fix it
in theory.
I tested on my Dell touch monitor which is in hybrid mode & sends 5
touches at a time, but can split across two packets to send up to 10
touches. It sends (0, 0) for the remaining slots when there are 6-9
touch points, but confirmed that there was no regression.

## Description of change
Game expects primary monitor to be in 90 deg rotation, and does the
touch calculation accordingly.
If the user does 270 deg rotation ("portrait, flipped") then the game's
touch calculation is flipped upside down. Detect this and provide the
fixed up values in the touch hook.
## Testing
Tested with SDVX in 90 deg, 270 deg rotation, and 1080p, forced 1440p.
