Buffer based OLED panning, write byte to buffer at arbitrary index (#8055)
* Add buffer based single line pan, arbitrary byte write to buffer * Change dirty mask to inverse of OLED_BLOCK_TYPE for future proofing larger buffer sizes * Updating docs to include new functions * Updating to clarify scroll vs pan
