Comet46 add support for OLED (#4745)
* Add OLED support for Comet46 * fix length of char "name" of keylogger.c * update ssd1306 * fix rules.mk * update led-receiver keymap * Update OLED related code * add mod_state_reader & modify led_state_reader * Update OLED related files * Update kemaps * Update readme * change default-oled-display to default * Add OSM compatibility to mod_state_reader * Code formatting * Use PROGMEM to store code_to_name * Clean up satt keymap * Rename default-led keymap to defult-rgbled
