show coordinates on each square of the board

[Bobkingmen3]

Currently the only option for board coordinates is http://prntscr.com/qccr44
Can we get an option call link "In squares" which puts all the names like g2 and e4 in the squares on the board, it would really help with practicing for some of us. If they were little and in the corners like they are now this wouldn't get in the way of the pieces.

Currently the only way to do this is by editing in a transparent background more on that here https://lichess.org/forum/general-chess-discussion/are-custom-boards-allowed-on-lichess?page=1

Closing in favor of newer duplicate #6861, which has more details.
