[Keymap] Improvements to KidBrazil keymap to better handle OLED/LED Matrix timeout. (#7688)
* Added KidBrazil custom keymap for CRKBD -Custom Font -Custom OLED output * Added missing readme * Oled Timeout Update for KidBrazil Keymap (#1) * Setup Oled timeout based on simple timer * Cleaned up comments and added timeout for LEDs * Fixed some small errors * Updated oled timout with matrix scan * Updated oled timout with matrix scan * Update withou eeprom * Update timer code * Use process user instead of keymap * Added ifdef to protect oledtimer * Updated with half timeout state for logo * Removed middle tier timer * Final cleanup of unused files * Updated code as per suggestions & requests * Second round of revisions * Updated keymap to better handle LED timeout - Added boolean to hold LED state - Added init function to set rgb to known state - Modified RGB_TOG to work with noeeprom commands * Finished adding the timeout for OLED and testing on CRKBD * Updated documentation * fixed the timeout logic so it works as intended * Update keyboards/crkbd/keymaps/kidbrazil/README.md
