Template handling

[T0jan]

This pull request expands the handling of parameters and templates:

• introducing wildcard processing to templates (came from Using custom name as component name #144)
• allow adjusting parameters in Ki-nTree

For performance reasons I also added the option for users to skip the check for existing parts in InvenTree as this check takes quite significant amounts of time for bigger categories.

I also updated the requirements to the latest inventree API version and the latest working version of flet.

Sweet, thanks @T0jan I'll give it a shot soon 👍

Btw I think poetry requirements need to be updated too, it is used to build and upload to PyPI.

Also, Inventree 0.12.6 just landed, maybe worth a shot to bring back master in the CI?

[T0jan]

checked with InvenTree 0.12.6 and saw no issues so back to stable it is. we just have to keep in mind to add the necessary environment variable once 0.13.0 drops.

Also sorry for the missing poetry requirement update, completely forgot about that. should be fixed now.

No problem at all, thanks for testing with InvenTree master, I think I can test it out next week ;)
