Blender 2.83 compatibility fix

[Jerakin]

README says the minimum supported blender version is 2.83.

The encoding argument for basicConfig wasn't added until python 3.9.

This doesn't seem to be enough to make 2.83 to work.

I am still getting this error

There is a PR that would (partially) fix this, see #128 (comment)

is it worth adding more code, to support such an old version of blender?
i know it's only a few lines in this case.

i worry that code complexity stacks up fast, and keeping bqt lean makes it more maintable.
what do you think?
perhaps we could instead update the minimum version in the readme, and provide instructions on disabling logging to run it on older versions.

[Jerakin]

I 100% believe support should be dropped. This PR spawned from testing on versions mentioned that bqt supports.

Personally, I would set minimum version to something that's still under LTS from Blender (that would be 4.2), however we do know that a lot of productions might not be very flexible when updating Blender, the addon might also happen to work in older - but that shouldn't be something that we need to test for.

I would remove the whole Requirement section and add something like this at the top "bqt is tested against the oldest Blender LTS version still receiving support"

ok closing this PR then
