Merge rust-bitcoin/rust-bitcoin#1844: make bip21 schema lowercase 

8835d5d2f1 make bip21 schema lowercase (Riccardo Casatta)

Pull request description:

  The spec RFC3986 specifies the scheme is case insensitive and we were uppercasing to optimize QR code representation.
  Unfortunately, common platform such as Android seems to fail to recognize uppercase schema, so for compatibility reason we use lowercase.

  close #1843
