Description
Currently the fitting region is defined by the ``fitshape`` parameter which defines a rectangular region around the (initial guess) center of the source.
It would be great to be able to perform the fit in a circular region.
I see this being implemented by allowing ``fitshape`` to be an ``CirclePixelRegion`` (from ``regions``) object which defines the fitting region.
Contributor guide
Research direction
Locate the PSF Photometry entry point and trace how the fitshape parameter currently defines the rectangular fitting region. Determine how a regions CirclePixelRegion should define the fitting area, then add coverage for circular fits while preserving rectangular behavior.
