aiohttp 3.7.4 isn't compatible with asyncio in Python 3.10

[maybe-sybr]

I mentioned this on Discord a couple of months ago, but have only just gotten back into hacking on the FSR code. This issue manifests as a TypeError in aiohttp when you hit ctrl-C to interrupt the script, like so:

yarn run v1.22.18
$ cd server && venv/bin/python server.py
/home/maybe/dev/fsr/fsr/webui/server/server.py:327: DeprecationWarning: There is no current event loop
  main_thread_loop = asyncio.get_event_loop()

    asyncio.gather(*to_cancel, loop=loop, return_exceptions=True)
TypeError: gather() got an unexpected keyword argument 'loop'

Per aio-libs/aiohttp#5905, this just looks like the dependency in requirements.txt needs to be bumped. Installing the newer releases of aiohttp and async-timeout (>= 4.0 seems necessary) fixes the ^C issue, but causes something else to break silently so that sensor values don't get reported to the UI. The value bars and the time plot both sit at 0, even though I apply pressure to my test sensor.

No sure what the breakage with the value reporting is, if I work it out I'll follow up here or make another issue.

Seems to have something to do with this code being deprecated
