Major upgrades to Petrosian workflow. It generalizes the Petrsoian profiles to use any eta and epsilon values.
This PR introduces:
A new option to address low signal-to-noise ratio issues when measuring r_99 by allowing the use of r_80. While r_80 provides good estimates of r_50 (r_e), it can sometimes result in an overestimation of r_99. To ensure accuracy, correction grids can be utilized to estimate r_99 from r_80. However, we maintain the Petrosian measurement philosophy that correction grids should be reserved for high-precision measurements. Therefore more analytical and testing work is needed before this PR can be merged into production.
Error estimates for all Petrosian Radii according to Strauss et. al 2002 Appendix A.3.
Saving/reading profiles to/from file.
Grid generation now has multi-processing support.
More work is needed to:
Make correction to 1D radial profiles. This may be out of the scope of this PR.
Other Changes
Remove kernel key word from segmentation functions since PhotUtils no longer accepts them.
order_cat moved to segmentation sub-module.
source_photometry moved to segmentation sub-module.
