make printing palatable

[jchorl]

There's a fair amount of hacked up css surgery going on here. I added comments for what each part does. I'm super flexible on where this code should go, how we should organize it, etc. This is just a first pass. Please provide feedback!

@ewels I think this is the last of my PRs :P

You can see from the examples what it does. Np if you want to play around with it, it feels extremely hacky. Fwiw, these were the configs I was using locally. Now that we have css overrides, I can just apply these myself, so no rush ;)

It mostly feels bad that it makes multiqc much more fragile. If the html changes, the print styling will almost certainly break...

I wouldn't be offended if you didn't want to merge.

Love this! I have always neglected PDF exports and sort of as an extension, printing. Now that I see what you've done here I'm wondering why.. Very simple addition and makes a huge improvement to the output 🖨️ ✨

If the html changes, the print styling will almost certainly break...

Yeah, but I can't see that this would be any worse than the current state of not having any print styling.. So not really a big issue as far as I can see (also the template rarely changes these days).

I was a bit confused at first as I couldn't see some of the effects when testing locally. Then I realised that not all the classes had been propagated through all of the templates. I guess you're mostly using -t simple, but I see no reason why the default template can't also look nice when printed. So I ported (most of) the new class names and markup over to all templates.

I've also had a bit of a play and added a bunch of additional CSS, mostly for stuff in the default interactive template. For example, making tables dumb and entirely visible and so on. Looking great now!

Black CI is failing but seems to be due to an issue with the docker container. Passes without issue locally ✅
