Create a function to allow the "merging" of multiple auths

[Badgerati]

Describe the Change

This is from #575.

Could it be possible to have some Merge-PodeAuth function, which would allow the merging of multiple auth methods?

For example:

Merge-PodeAuth -Name -Auths[] <-All> <-One>

This will return a "merged" auth type usable on Routes, and you can either have All auths needed to pass, or just One to pass.
