datatest-stable 0.3.0

Added

• Support for embedding data into the test binary via an optional include-dir
  feature. For more information and recommendations for when to use this, see the
  readme.

Changed

• The macro call format has changed to:

  datatest_stable::harness! {
      { test = fn_name, path = &include_dir!("path/to/data"), pattern = r"^.*$" },
      // ...
  }

  This is both a nicer format for expressing multiple tests, and a signal to
  indicate the other breaking changes in this release.

• Regex patterns now match against the path relative to the include directory, rather
  than paths with respect to the crate root. This change was made for uniformity with the
  include_dir implementation.

• On Windows, paths are now universally normalized to use forward slashes. This change
  was made to ensure that test names and paths are consistent across platforms.
