a762a89b48 Add documentation to Sequence::is_final (Tobin C. Harding)
b1490a26ea Move enables_absolute_lock_time method (Tobin C. Harding)
Pull request description:
The term "final" is an archaic Bitcoin term however it is well used, it exists in Bitcoin Core code as well as in various bips. To help folks new to Bitcoin add documentation to the `is_final` method including historical notes.
Note, this does _not_ deprecate `is_final` - while writing the notes I found the term "final" in enough official places that I think its fair game to keep the term, some things people just have to learn, we can definitely help with that learning though.
