basic outline of a with Auth filter

[FreeMasen]

This is a very basic outline of what a possible with filter might look like for authorization.

Primarily this is a copy of src/filters/cors.rs modified enough to make authorization work at a somewhat rudimentary level.

A few things that I am not super happy with but do not know the ideal way to solve.

• Export of the trait Authorizer, this is not something that is done anywhere else in the project so doesn't feel like the right path forward.
• Whatever structure is setup moving forward should probably be returning a Future instead of a Result, especially not a Result<(), ()>
• As noted by the CI failures, my understanding of what is required when wrapping isn't as great as it could be.
