haskell/core-libraries-committee#33 : Remove uses of MonadFail (ST _)

Also:

  • There was a use of fail for Maybe which is entirely pointless.
  • Type signatures for some local functions in NewDFA/Engine_FA

There was a use of `fail` for `Maybe` which is entirely pointless.

- Tested with GHC 7.4 - 9.4

### 1.3.1.4

- Fix parsing of dashes in bracket expressions, e.g. `[-a-z]` ([#1](haskell-hvr/regex-tdfa#1))

_2022-02-19, Andreas Abel_
- No longer rely on the `MonadFail` instance for `ST`
  (future `base` library change, see [#29](haskell-hvr/regex-tdfa#29)).
- Silence warning `incomplete-uni-patterns` (GHC >= 9.2).
- Import from `Data.List` explicitly or qualified (warning `compat-unqualified-imports`).
- Import from `Control.Monad` to allow `mtl-2.3` in its `rc3` incarnation.
