Replace Parsec with Megaparsec (see #289 ) ( #366 )
...
* Replace Parsec with Megaparsec (see #289 )
This builds upon PR #289 by @rasendubi
* Revert renaming of parseWithState to parseWithCtx
* Fix doctests
* Update for Megaparsec 5
* Specialize parser to improve performance
* Pretty print errors
* Swap StateT and ParsecT
This is necessary to get the correct backtracking behavior, i.e. discard
state changes if the parsing fails.

10% more allocation, but 35% lower maximum residency, and slightly quicker.

The first of several conversions from String to (strict) Text, hopefully
reducing space and time usage.
This one shows a small improvement, with GHC 7.10.3 and text-1.2.2.1:
