Remove the orphaned lcd-panel-cgram.rst file and clean up its entry from the admin-guide index to prevent any future Sphinx broken links.

The escape code to define a new character is -'\e[LG' followed by one digit from 0 to 7, representing the character -number, and up to 8 couples of hex digits terminated by a semi-colon -(';'). Each couple of digits represents a line, with 1-bits for each -illuminated pixel with LSB on the right. Lines are numbered from the -top of the character to the bottom.
