Drop Poetry in favor of Hatch

[akx]

This PR switches the packaging backend to Hatch. I think Hatch is the better, simpler option for libraries, since one doesn't actually have much use for a lockfile anyway in one.

The publish procedure changes from poetry publish to hatch publish, approximately. 😁

Additionally,

• it sets somewhat looser required version ranges for everything
• it removes some unnecessary requirements
  • blackness is handled by pre-commit
  • tqdm is never even imported here
• moves the requests requirement to the feelinglucky extra. (Chances are, of course, that requests will be installed in practically any environment).
