Add E-Ink display driver and chip detection for VME213
- Implemented LCMEN2R13EFC1 display driver in src/LCMEN2R13EFC1.h, supporting full and fast refresh modes. - Added E-Ink chip detection functionality in src/einkDetect_VME213.h to differentiate between LCMEN213EFC1 and E0213A367. - Included GNU General Public License text in tools/LICENSE.txt. - Added arduino-cli executable to tools directory.
