Report 4.2.0 from QueryPath::VERSION and deprecate the version constants

VERSION and VERSION_MAJOR were left at 3.2.2 and 3 through the whole
4.x line. Set them to the latest release, deprecate them in favour of
Composer's InstalledVersions API, and add tests that tie VERSION to the
newest release heading in CHANGELOG.md so they cannot drift again.

Add the missing 4.2.0 changelog section.

 - Fix `writeHTML()` throwing `QueryPath\ParseException` instead of `QueryPath\IOException` when the file cannot be written, as `writeXML()` and `writeHTML5()` do (issue #92). `IOException` extends `ParseException`, so existing `catch (ParseException $e)` blocks still catch it
 - Fix `css()` merging the inline styles of every matched element and writing the combined result back to all of them. The new declarations are now merged into each element's own `style` attribute (issue #77)
 - Fix `not()` keeping only the given nodes, instead of removing them, when passed an `SplObjectStorage` such as `get(null, true)` returns (issue #75)
+- Fix `QueryPath::VERSION` and `QueryPath::VERSION_MAJOR` still reporting `3.2.2` and `3`. They now report `4.2.0` and `4`, and both are deprecated in favour of `\Composer\InstalledVersions::getPrettyVersion('gravitypdf/querypath')`, which cannot drift from the installed version (issue #83)
