make swipe exceptions user-configurable

[zanna-37]

Enhancements

Provide a way to bypass the default hard-coded exceptions

This could be easily done with a flag use_default_exceptions which defaults to true.

swipe_nav:
  use_default_exceptions: false

This flag would be quite useless alone, therefore the user should be able to add custom exceptions.

Provide a way for the user to add exceptions via CSS selectors

swipe_nav:
  custom_exceptions:
    - div.class1.class2
    - special-tag
    - g.my-special-class

Drawbacks

In this implementation, when setting use_default_exceptions to false the user needs to manually copy the hard-coded exception list and put them as custom_exceptions. And although it is suboptimal, it is not that uncommon. Home Assistant default configuration works in the same way.
I think that creating a system of inclusions/exclusions would only complicate things with little gain since I suspect that use_default_exceptions would only be used in rare circumstances.

I think that this should be implemented only when the swipe exception format is considered stable, to avoid breaking-changes down the road.

Ahhh i need it so much! What about using css selectors for the custom exceptions?

[zanna-37]

css selectors are an interesting suggestion. They could replace the current method so we don't have to reinvent the wheel. 🤔

[zanna-37]

CSS selectors are now implemented in v1.5.0, but before enabling user-defined exceptions I would like to gather more opinions and I would like to wait until the exception format is stable, to avoid breaking-changes in the future.

In the meantime, feel free to propose pull requests with other exceptions, so everyone can benefit from them.
