Increase sprite height from 14 to 16

In FireRed, the lower case p and upper case P share the same ring
section. With a sprite height of 14, lower case's lower section is cut
off and causes it to match with any upper case P, stopping text
accumulation. This fixes the issue by increasing the sprite height.
Add accel print tile function for debugging matches
Factor out extract tile from identify sprites
Add identify sprites solid line below requirement

This stops apostrophes from being recognized as commas by enforcing that
there are no artifacts below the comma. If there are artifacts, such as
letters, it is likely it is actually an apostrophe and the line must
advance.
Move the line above requirement down one pixel

This fixes some edge causes with apostrophes.
