Subject: paddle::verify_signature(): Extract signature from params

Make it easier on users by not requiring them to pass a signature into
the method. This means they don't have to extract the `p_signature`
param and base64 decode it themselves.

Essentially, we want to move the code from `request` that removes the
`p_signature` key and base64 decodes it into the
`paddle::verify_signature()` function.

We need to make the string-like type params in `verify_signature()`
conform additionally to `PartialEq<str>` and `PartialOrd`. Doing so
allows us to find the key "p_signature".

To remove the `p_signature` param from the iterator, we partition it
into two iterators: one for the `p_signature` entry, and another for the
rest. We then extract the value of `p_signature` and base64 decode it
for verification.

Add a new error type in case no `p_signature` entry is found in the
iterator.
