dsda: fix horizontal mouse range 

the core uses 2 bytes, but if we use that range then raw mouse input is automatically recalibrated somehow and sends values multiplied by 272. that way maximum actual value is 120 (after dividing the range cap by 272), which is even more limiting than shorttics. and min value is 272 itself, which is not very useful if we have to divide it, because we need it to be 1!

the range of [-180, 180] is somehow the highest range that still gives minimal movement of 1, while providing maximum room for bigger movement.
