Support large board size

[cryptsport]

you can add support for katago for large boards - connecting the engine? and reading the "extended sgf" like
"location should a string like "C4" the same as in the GTP protocol. KataGo also supports extended column coordinates locations beyond "Z", such as "AA", "AB", "AC", ... Alternatively one can also specify strings like "(0,13)" that explicitly give the integer X and Y coordinates."

to view games for boards larger than 52x52

I'm sorry, I'm not a computer programmer, so I can hardly make any changes to lizzie myself.
Almost all the updates so far are the result of using PR prepared by other people.
By mentioning the official lizzie Issues, the developer may create a nice PR.
