143 optimization

🔍 Type of Change

optimization getting out of hand, so splitting these into separate PRs.

1. asset validation is expensive as hell. make it optional.
2. residual only grabs the latest frame
3. residual goes to zero in the new component area
   4. residual uses buffer (double-circular)
4. change dim / coord names to make indexing with only dim possible
5. optimize footprint update to use scipy sparse
6. optimize trace update to use numpy
7. remove boundary expansion from footprint update
8. optimize overlaps update to use scipy operations
9. optimize negative residual fit to use scipy operations
10. optimize unlayered footprint search to use nonzero coords
11. catalog - handle tiny shapes that weren't merged (remove them)
    13. residual learns instead of one-shot flooring to prevent outlier pixels from messing up the whole trace
12. toy shapes asymmetric
