Merge branch 'release-v0.7.3'

* release-v0.7.3:
  Bump version and update changelog
  Stop typechecking after a parse error in some file (avoid invalid cache)
  Fix warning
  Make formatFile strict
  Clean up formatting code
  Check Rzk formatting for all languages before rendering MkDocs
  Apply autoformatting to docs
  Make safer resolveLayout, use that in the formatter, drop deepseq dependency
  Convert `formatTextEdits` to IO to catch errors
  Add DeepSeq package to dependencies
  Add a couple of logs for errors while typechecking
  Split the space edits around bin ops into 2 to avoid overlapping with possible unicode edits
  Skip typechecking when the decls have not changed
  Add some tests for the formatter
  Install HSpec and configure HSpec-Discover
  Unignore the tests directory
