5f426d8667 Use 2 * bestMoveChanges. 
NNUE appears to provide a more stable eval than the classic eval,
so the time use dependencies on bestMoveChanges, fallingEval,
etc may need to change to make the best use of available time.
This change doubles the effect of totBestMoveChanges when giving
more time because the choice of best move is unstable.

additionally allow all options to be converted to string.
Without this, restoring of the options (multi_think.cpp:117) can't work.
