Async full-refresh for EInkDynamicDisplay (#3339)
* Move Wireless Paper V1.1 custom hibernate behavior to GxEPD2 * Async full-refresh for EInkDynamicDisplay * initial config for T-Echo * formatting responds to https://github.com/meshtastic/firmware/pull/3339#discussion_r1518175434 * increase fast-refresh limit for T-Echo https://github.com/meshtastic/firmware/pull/3339#issuecomment-1986245727 * change dependency from private repo to meshtastic/GxEPD2 --------- Co-authored-by: Ben Meadors <benmmeadors@gmail.com>pull/3374/head
