Warn on zero weight groups #9

Closed ryanzomorrodi closed 1 month ago

ryanzomorrodi commented 1 month ago

Currently, there is no check for zero weights,

unprojected mean_center returns empty geometry for each geographic area with no warning
projected mean_center returns a centroid (how this happens, I am not sure)
projected median_center returns a centroid

These are the next steps:

[x] This behavior should be unified
[x] There should be a warning for zero weight groups (maybe not a warning EVERY single time, but one warning with the number of zero weight group
[x] There should probably be a check for negative weights
[x] Add tests
