Enhanced per-tile vertical scroll [genesis_plus_gx_enhanced_vscroll]

Allows each individual cell to be scrolled vertically, instead of 16px 2-cell, by averaging out with the vscroll value of the neighbouring cell. This hack only applies to few games that use 2-cell vertical scroll mode.

NOTE: The scroll limit is set to 16
