// ParseWithClaims parses, validates, and verifies like Parse, but supplies a default object implementing the Claims
// interface. This provides default values which can be overridden and allows a caller to use their own type, rather
// than the default MapClaims implementation of Claims.
//
// Note: If you provide a custom claim implementation that embeds one of the standard claims (such as RegisteredClaims),
// make sure that a) you either embed a non-pointer version of the claims or b) if you are using a pointer, allocate the
// proper memory for it before passing in the overall claims, otherwise you might run into a panic.

// WARNING: Don't use this method unless you know what you're doing.
//
// It's only ever useful in cases where you know the signature is valid (because it has
// been checked previously in the stack) and you want to extract values from it.
