Unclear how to compare generic ranges against equalitiy

[Viatorus]

By reading the docs as linked here:

https://github.com/catchorg/Catch2/blob/devel/docs/matchers.md#generic-range-matchers

I don't get what the required include is or the API to compare two generic ranges.

I would like to compare std::span's against equality, like this:

CHECK_THAT(std::span<char>{}, Catch::Matchers::Equals(std::span<char>{}));

But this doesn't compile. Isn't this supported or do I use the wrong syntax?

Maybe something like this could be implemented? Its not perfect, but here is a rough attempt.

Isn't this very similar to #2473?

This works in the current release still, thank you for the easy work around.

@Viatorus, if you are still looking/wondering, commit https://github.com/catchorg/Catch2/commit/efca9a0f1826885c1574ed44fc37c8d82ded4546 introduces algorithm into the dev branch.
