Merge rust-bitcoin/rust-bitcoin#774: Change type of final script witness to Witness from Vec<Vec<u8>> 

9a8ab3f3ff Change type of final script witness to Witness from Vec<Vec<u8>> (sanket1729)

Pull request description:

  Doing this would certainly help APIs downstream that operate on &Witness because they would not conversion from &Vec<Vec<u8>> to &Witness.
