Merge rust-bitcoin/rust-bitcoin#790: Re-export psbt module from root level

b138428 Re-export public map types from root level (Tobin Harding)

Pull request description:

  We currently have the `map` module private but containing a bunch of types that are needed in the public API (specifically in a `PartiallySignedTransaction`).

  To give access to them re-export the `util::psbt` module at the root level.

  Found while testing `master` with `rust-miniscript`.
