species v0.5.2

• Several enhancements with the isochrone functionalities
• Support for Sonora Bobcat isochrones (add_isochrones('sonora'))
• Use of the parallax parameter in addition to distance (e.g. in add_object, add_companion, SyntheticPhotometry)
• The analysis routines (e.g. FitModel, EmissionLine, AtmosphericRetrieval) use by default the parallax as free parameter with a Gaussian prior
• Removed the run_mcmc (i.e. using emcee) method in FitModel, because it was no longer maintained and it is recommended to use the nested sampling routines
• Support for Koester white dwarf spectra (for calibration purpose)
• Options for retrieving parametrized cloud opacities with AtmosphericRetrieval
• Included the interp_method parameter in the configuration file for setting the method for the grid interpolation
• Improvements with the labels in various plots and the font style
• Many minor enhancements, maintenance, and updated tutorials and documentation
