Merge rust-bitcoin/rust-bitcoin#1565: Reduce usage of `FromHex` 

32ca6cc320 Remove hex_from_slice and display Sighash forwards (Tobin C. Harding)
a308e1e2ea Remove FromHex for all types except Vec and array (Tobin C. Harding)
3e70c01826 Manually format a bunch of vecs (Tobin C. Harding)
83e1c40c4d Remove script:: prefix from unambiguous types (Tobin C. Harding)
5ab5c264d2 Use fully qualified path in macro (Tobin C. Harding)
7e85452cd9 hashes: Implement std::error::Error (Tobin C. Harding)
5e3abc5e11 Fix feature gating on unit tests (Tobin C. Harding)
3344cf6be2 Favour $reverse instead of $reversed (Tobin C. Harding)

Pull request description:

  This work started out, as the branch name suggests, as an effort to use the `hex_lit` crate. But once I got to this stage it seems that the `hex!` macro we have provides different, useful, functionality than the `hex_lit::hex!` macro (it allows usage with non-consts). So I'm unsure if we want to remove it now.

  - Patches 1 - 6 are preparatory clean ups
  - Patch 7 reduces usage of  `FromHex`, please see git log for full description
  - Patch 8 removes `hex_from_slice` and fixes a bug in how we display `Sighash`
