Vendor dependencies for 0.3.0 release

+Test data was taken from the Go distribution, which was in turn taken from the
+testregex test suite:
+
+  http://web.archive.org/web/20150925124103/http://www2.research.att.com/~astopen/testregex/testregex.html
+
+Unfortunately, the original web site now appears dead, but the test data lives
+on.
+
+The LICENSE in this directory corresponds to the LICENSE that the data was
+originally released under.
+
+The tests themselves were modified for RE2/Go (and marked as such). A
+couple were modified further by me (Andrew Gallant) and marked with 'Rust'.
+
+After some number of years, these tests were transformed into a TOML format
+using the 'regex-cli generate fowler' command. To re-generate the
+TOML files, run the following from the root of this repository:
+
+  regex-cli generate fowler tests/data/fowler tests/data/fowler/dat/*.dat
+
+This assumes that you have 'regex-cli' installed. See 'regex-cli/README.md'
+from the root of the repository for more information.
+
+This brings the Fowler tests into a more "sensible" structured format in which
+other tests can be written such that they aren't write-only.
