Research direction
No files or tests are named. Start by reproducing the darkness in tiles with buckets around z22 or higher, then inspect the encoding and density-quantile behavior described in the issue. Done means high-zoom tiles no longer appear too dark while point locations and density representation remain correct.

Description
High zoom tiles (with buckets of around z22 or higher) are too dark because a lot of points are snapped to roads instead of reported at their natural locations.
Possible fixes:
- Add positional noise during encoding
- Detect and discard exact duplicate locations
- Make better use of density quantiles to highlight lower densities at these zooms
- Just change the curve at these zooms instead of bothering with the quantile calculation
