masterMindGame: demo bigLolly track rendering a solved game of Mastermind on hg38

Demonstrates the lolly track type by mapping a Mastermind board onto it:
score field is the board row, genomic position is the peg column, itemRgb is
the peg color, and the size field separates the large code pegs from the
small feedback key pegs. Guesses come from a consistent-candidate solver so
the black/white feedback is real. Included alpha-only.
