Standalone plotting functions

[ahmed-f-alrefaie]

The TauREx plotter is a little big on the tooth and I think it would be worth moving a lot of the functions into standalone plotting functions that people can use outside of the HDF5 format. I'm using a notebook but I am having to reimplement the functions in Plotter to use them directly in the notebook

Proposal

There should be a taurex.plot module that contains useful plotting functions. For example:

import taurex.plot as tplot

fig, ax = plt.subplots()

im = tplot.plot_optical_depth(ax, tau, pressure, wavelengths)

plt.show()

Which would plot the optical depth with wavelengths and pressures:

This is the optical depth without the contribtution.
To do this we could write a seperate function and combine it with the optical depth:

tplot.plot_optical_depth(ax1, tau, pressure, wavelengths)
tplot.plot_depth_contrib(ax2, tau, pressure)

Again we could introduce additional arguments to matplotlib via kwargs etc for colormaps, titles, wavelength/pressure ranges, units etc etc.

This would significantly simplify the Plotter class as well .
