SHA256 counter tests.

The tests verify that the SHA256 counter doesn't wrap around at message length 2^i bytes for i = 20, ..., 33. This wide range aims at being independent of the implementation of the counter and it catches multiple natural 32-bit overflows (e.g., counting bits, counting bytes, counting blocks, ...).

The test vectors have been generated using following Python script which relies on https://github.com/cloudtools/sha256/ (v0.3 on Python v3.10.2).
