0.25

The 0.25 release contains a combination of all-round fixes, documentation, and polishing:

• Restore Test.make's max_fail parameter which was accidentally broken in 0.18
• Adjust stats computation of average and standard deviation to
  limit precision loss, print both using scientific notation, and
  workaround MinGW float printing to also pass expect tests
• Fix dune snippets missing a language specifier in README.adoc
  causing asciidoc to error
• Add a note to QCheck{,2.Gen}.small_int_corners and QCheck{,2}.Gen.graft_corners
  about internal state, and fix a range of documentation reference warnings
• Reorganize and polish the README, rewrite it to use qcheck-core, and add
  a QCheck2 integrated shrinking example
• Document QCHECK_MSG_INTERVAL introduced in 0.20
• Add QCheck{,2}.Gen.map{4,5} combinators

The accompanying ppx_deriving_qcheck.0.7 release offers:

• Support ppxlib.0.36.0 based on the OCaml 5.2 AST
