This tests error cases for ppx_cstruct.

It only deals with the errors raised by the ppx itself (such as when the type is not supported), not errors in the generated code.

To add a test case:

• create a file in this directory named something.ml with the error case
• create an empty file named something.ml.expected
• don't forget to add these files to git
• run dune runtest: it displays a diff on dune.inc
• run dune promote: it updates dune.inc with the generated test case
• run dune runtest: it runs the test and displays a diff against the empty expected output
• run dune promote: it updates something.ml.expected
