Pyimfit

Added
Now based on version 1.9 of Imfit.

Models (including current parameter values) can now be described by a dict-based format;
dict-based model descriptions (including current best-fit parameter values) can be
returned by Imfit instances as well, via their getModelAsDict method.

Imfit.fit and Imfit.doFit can now take an optional `ftol` parameter (same as the `--ftol`
parameter for the command-line `imfit` program -- controls fractional tolerance of fit statistics
as a convergence criterion during the fitting process).

Pre-compiled versions for Python versions 3.9--3.11 on macOS.

Changed
The interface to the FunctionSetDescription class has changed: the "name" parameter is
now optional (and defaults to None).

Fixed
Imfit now correctly loads models with PointSource and PointSourceRot image functions.

Added
Added "ftol" as optional input parameter for Imfit.doFit() and Imfit.fit().

Changed
The interface to the FunctionSetDescription class has changed: the "name" parameter is
now optional (and defaults to None).

Changed
Updated to use version 1.8 of Imfit, including new image functions (GaussianRingAz, FlatBar)
and function labels in config files.

Added
Pre-compiled version for Python 3.8 on macOS. Minor added checks for correct length of
parameter vectors as inputs to methods in Imfit class.

Added
Imfit objects now return a FitResult object containing summary information about the
fit when the doFit method is called.

Added MakePsfOversampler() convenience function to create PsfOversampling objects
(automatically applies FixImage to oversampled PSF image array).

Changed
Added automatic conversion (via FixImage) of input PSF images when instantiating Imfit objects.
