Move parser + parser tests out to own package.

We move some types out that are necessary as well and then
re-export and specialise them in the core Haddock.

Reason for moving out spec tests is that if we're working on the parser,
we can simply work on that and we can ignore the rest of Haddock. The
downside is that it's a little inconvenient if at the end of the day we
want to see that everything passes.

--- | The core parser type.  This is parameterised over the type @t@ of
--- string being processed.
---
--- This type is an instance of the following classes:
---
--- * 'Monad', where 'fail' throws an exception (i.e. fails) with an
---   error message.
---
--- * 'Functor' and 'Applicative', which follow the usual definitions.
---
--- * 'MonadPlus', where 'mzero' fails (with no error message) and
---   'mplus' executes the right-hand parser if the left-hand one
---   fails.  When the parser on the right executes, the input is reset
---   to the same state as the parser on the left started with. (In
---   other words, Attoparsec is a backtracking parser that supports
---   arbitrary lookahead.)
---
--- * 'Alternative', which follows 'MonadPlus'.
