Bumps pymodbus[serial] from 3.11.4 to 3.12.0.

Release notes

Sourced from pymodbus[serial]'s releases.

pymodbus v3.12.0

This release contains a lot of smaller (but still important) bug fixes, and 2 big new items:

  • SimData/SimDevice are not released and integrated. This is a modern way of defining data storage for the server. The old datastore classes will disappear in v4.0.0 or a bit later.
  • All internal import paths are now relative. This allows pymodbus to be added as a subproject to your repo with your a name of your choosing, and thus making your project independent of which pymodbus version other shared projects use (think e.g. HomeAssistant).

We are also please to welcome 4 new contributors, who we hope will contribute more. A big thanks to all that have helped make this release happen.

Please remember this is an Y type release (in our X.Y.Z scheme) so please remember to check API_CHANGES.RST to see if your project needs to make small changes.
