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
