textproc/hs-commonmark: 0.2.2

0.2.2
* Blocks: export getParentListType [API change].
* Require unicode-data >= 0.3.
* Change mkFormattingSpecMap so it integrates different FormattingSpecs
  that use the same character (#87). Otherwise we have problems if you have
  one formatting spec that reacts to single delimiters and another that
  reacts to pairs; if the first fails to match, the fallback behavior is
  produced and the second never matches.
* Use unicode-data's faster versions of Data.Char functions. This speeds up
  benchmarks for tokenize considerably; little difference in other
  benchmarks. unicode-data is already a transitive dependency, via
  unicode-transforms.
* Increase strictness in tokenize/go.
* Remove legacy cpp needed to support ghc < 8.4.
