Added dpi and savepdf options to comparison report for publications

[ledm]

Colin asked for a higher resolution version of the images, so I added an option is the report maker to set image resolution in dpi, and also a flag to save images as a pdf.

I'm definitely getting my money's worth out of @valeriupredoi this week! Thanks for the hard work mate!

only that you're not paying me a single penny though 🤣 Lemme have a looksee in a jiffy 👍

fine by me, but I'd add a default value for dpi, and I'd also add a check on how dpi is specified by the user - if it's not like eg dpi=200 and it's dpi=200x300 that should probably be caught before Matplotlib throws a hissy (basically try: int(dpi) else: raise ValueError("that need be an int you dummy")) - up to you

[ledm]

If we leave the dpi as the default value (None) then the image will be saved using the user's default dpi settings, which can be changes using:

plt.rcParams['savefig.dpi'] = 300
