pngToLolly: new utility to render a PNG as a bigLolly dot-mosaic track

Each opaque pixel of the downscaled image becomes one stemless lolly: column
-> genomic position, row -> lolly value, pixel color -> itemRgb, and local
image detail varies the dot size. Emits a ready-to-build hub plus makeHub.sh.
By default writes a self-contained synthetic assembly hub; with -db/-pos it
lays the mosaic across a window of an existing assembly as a track hub. Dot
sizes use the browser's standard percent-of-height lolly sizing. Adds a README
covering usage, options, and the canvas-size/dot-size trade-off.
