Stricter Solve Assist

[biobak64]

Solve assist is a pretty good addition, however I think it is a bit too lenient with the boards it solves.
I would love something similar, but that only solves boards in which all five letters have been guessed in the right place previously (Boards where all five ghost letters appear when "show input hints" is enabled).

These are basically already solved, so it would be nice if the game could auto-guess them for you, without also auto-guessing boards where the solution could be deducted but has not fully been found yet.
