Update README

[willtebbutt]

Summary

The priorities seemed a bit out of date and, given that we don't really have a coherant list of priorities for this package at the minute, I figured it best to remove them for now.

In their place I propose a related work section.

Proposed changes

• Remove priority list in README
• Add related work section to README

What alternatives have you considered?

Trying to update the priorities to reflect where we are today. This turned out not to be possible, owing to a lack of a clear set of priorities.

Breaking changes

None

Seems sensible!

Would you want to keep a note that KernelFunctions is and will be AD-compatible though?

Good point. Yes, I want that.

@theogf @st-- added AD reference and removed reference to input transformations, because I'm not sure that input transformations will mean much to users first encountering the package. Happy to revert if the latter change is at all contentious.

@theogf @st-- happy with the state of this now?

[willtebbutt]

Thanks for the review @st-- @theogf @Crown421 . Will merge as-is (once CI passes) -- please open another PR if there's anything else that needs changing.
