Simple color scaling/adjustment

[Lucent]

This is a fun tool that reveals interesting patterns, like not posting 4 Saturdays in a row.

Would you consider a manual or logarithmic scaling setting, even as a hidden variable or command? For example, Ptable allows selection of the start and end color and log vs. linear. If you went crazy and made 60 posts only one day, the dynamic range of colors for the remainder of the chart flattens.

One other minor suggestion. I'd prefer .react-calendar-heatmap .color-empty be pure white/background.

sounds fun! feel free to open a PR and/or fork it, right now my focus is elsewhere when it comes to my projects
