Bug when trying to checkmate

[Dopplerian]

For the following input command:
./walleye -P -f '7k/4Q3/6K1/8/8/8/8/8 w - - 0 1'
It first does a search to depth 99, which is unneeded since it is clearly a mate in 1, and then prints the same board over and over instead of terminating program execution.

There seems to be an issue in the CLI version where mate does not terminate the program, that is certainly a bug.

As far as always searching to depth 99, that is just an artifact of how I do the time management where the engine just looks until its out of time without checking for an early exit, this will likely be kept as is
