Add finalizers predicate filter

[ivan-kiselev]

As per relevant discussion

@clux I had to relax hash constraints with + ?Sized as .finalizers() returns &[String] of unknown on compile time size and so compiler wasn't exactly happy about that, but doesn't seem to be affecting anything else.

Looks very sensible to me. Thanks a lot!
