Flipped the polarity in the `ltr303_advanced_test` to `False` on the int pin. This keeps the pin High until the interrupt triggers, then drops the pin to Low. Thanks kattni!

Fixed spelling errors and increased specificity for some variables and property names. Additionally flipped the polarity in the `ltr303_advanced_test` to `True` to work with attaching an LED to the int pin to see when it is triggered. Thanks kattni!

Variables changed:
- `ltr303.int_persistance` is now `ltr303.int_persistence`
