Pdspy

A number of minor updates and bugfixes to make the code work better. One more substantial addition is the ability to use visibilities['nphi'] and visibilities['nr'] in a config.py file to control the number of phi and r cells in a circular image when doing unstructured imaging fits.

A number of minor bugfixes to make version 2 of the code work better.

Drop the evolutionary tracks as part of the package as they were making the package too large.

Fixes pdspy.radmc3d.run.sed to match the new format from RADMC3D where "spectrum" is used to generate SED's at user defined wavelengths for the v2 version of pdspy.

Mostly a number of minor fixes to v2.0.0, including:

- Fix utils.load_results to load uncertainties properly
- Make sure disk-only plotting is working correctly in modeling.run_disk_model
- interferometry.readms now loads "corrected" columns without breaking
- Added an option to pick which polarizations to load in interferometry.readms. Defaults to "I"
- interferometry.interpolate_model now uses the C++ version of the unstructured galario algorithm

A major upgrade to pdspy, which is not backwards compatible to versions < 2.0.0. Updates include:

- x0, y0 now defined in the proper sense as opposed to backwards as they were before
- Position angles reported are now defined correctly, so no post-processing needed
- Supply the code directly with CASA MS files (requires Python 3.6 and CASA6)
- Fourier Transforms of model images are now done entirely with either GALARIO or TriFT, and an option to choose between them exists.
