Add move() function taking integers 0-63 about binbo

[DOBRO]

Describe please

[JMS55]

all_legal_moves() can provide moves as integers, but move() requires you to convert to a string like "e1:a2". It would be great to be able to use move() with integers as well, like move(server_pid, from, to).

Added fun binbo:index_move/3,4

Examples:
binbo:index_move(Pid, From, To)

binbo:index_move(Pid, From, To, 'q')
binbo:index_move(Pid, From, To, 'r')
binbo:index_move(Pid, From, To, 'b')
binbo:index_move(Pid, From, To, 'n')
