48623b4ceb lib: fix backtracking in periodexpr parser
- Simplify doctests for periodexpr.
- Besides consuming leading space consume ending space for periodexpr also.
- Drop implicit option (def, def) behaviour of periodexpr. I.e. disallow
  hledger reg -p '' and auto-transaction with heading just '~'.
- Slightly re-factor periodexpr.
- Ensure that reportinginterval doesn't consume trailing space.
  Useful if  we'll start disallowing periods like "every1stjan2009-".

d7d5f8a064 add support for megaparsec 6 (fixes #594)
Older megaparsec is still supported.
Also cleans up our custom parser types,
and some text (un)packing is done in different places
(possible performance impact).

4141067428 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.
