Updated YAML for all bestiary files

[aethertap]

This has a ton of yaml changes to make it work with the current version of fantasy statblocks. I ran some automatic tools and then went through and tried to patch up the rest of the issues by hand - as far as i can tell, they all load correctly now and display the right data. There are probably some formatting problems with things like randomizer tables that are embedded in the desc: values, but I did format several of those as well.

Thanks for the work you've put into this! It's awesome.

Literal lifesaver! I was just working on updating my obsidian as a noob and I couldn't figure out why they where not loading. I'll try these out.

There are still a few lingering issues with getting it to work on the initiative tracker - I'm working on that now (it has case-sensitive yaml keys for hp and ac, which means the capitalized ones in the current vault don't get picked up).
