Quality-of-life/automation improvements

• Option to run code based on tag used in -m argument (i.e. teb.py -m Vega; followed by teb.py -d Vega instead of teb.py -c Vega.yaml -p Vega_photometry_data.yaml etc.). Should still keep option to specify different files
• Routine to retrieve STILISM E(B-V) estimate if none provided
• Routine to retrieve Gaia parallax if none provided
• Option to automatically generate NIR FRP values based on starting values in main config file; i.e. just specify +/- range for each parameter and main code will deal with the rest. Still keep manual option
• Rosseland correction - at minimum, calculate % error on given radii and print warning for user to check they have the correct radii. Ideally, an automatic calculation, but it's easier said than done.
• Automatically estimate systematic error from the flux scale zero point (Bohlin) on finish
• Guidance (or suggestion) for alpha fraction could be useful

Also, for output plots, would be nice to have

• "distortion plot" for 0 distortion; just to check the state of the SED
• Plot magnitudes and flux ratios to check general trend before main fit begins
• Plot NIR flux ratio priors colour-Teff diagrams to check an appropriate sample is being used

• Automatic inclusion of Skymapper magnitudes could be nice, or at least a toggle option so users don't have to go figure out the values and zero points themselves.
• Correction to the GALEX zeropoints in certain magnitude ranges for NUV would be useful to include (as default or as option)
