Applied code checks

[photoniker]

I have applied checks and fixes onto the source code using pre_commit hooks:

• pyupgrade
• codespell
• fix-byte-order-marker

[photoniker]

For python unittest I see such fails:

• dataobject_np_conversion.py: `====================================================================== FAIL: test_continuousDataObject2NpArray ... (dataobject_np_conversion.DataObjectNpConversion.test_continuousDataObject2NpArray)

Traceback (most recent call last): File "c:\itom\sources\itom\python_unittests\dataobject_np_conversion.py", line 24, in ... test_continuousDataObject2NpArray self.assertIs(b1.base, a) AssertionError: (dataObject('uint8', [2 x 3 x 3], continuous: 1, owndata: 1), <capsule object NULL at ... 0x000002D908301B00>) is not dataObject('uint8', [2 x 3 x 3], continuous: 1, owndata: 1)`

• itom_jedilib.py: `====================================================================== FAIL: test_help_notypehints (itom_jedilib.ItomJediLibTest.test_help_notypehints) .

Traceback (most recent call last): File "c:\itom\sources\itom\python_unittests\itom_jedilib.py", line 229, in test_help_notypehints self.assertEqual(len(h), 0) AssertionError: 1 != 0`

@magro11 Can you run and check that unitttests?

Do we have a documentation on how to apply our pre-commit hooks?
