Rabbit, RabbitWithIV, HC128 and HC256 were producing incorrect results when `inString == outString` as reported in [GH #1231](https://github.com/weidai11/cryptopp/issues/1231). We added self tests to detect the failures, and cleared the failures.

The new tests also revealed HIGHT/CTR mode also has problems.

This bug will track HIGHT/CTR.

Title : HIGHT/CTR mode self test failures
Issue date:

--- start body ---
Rabbit, RabbitWithIV, HC128 and HC256 were producing incorrect results when `inString == outString` as reported in [GH #1231](https://github.com/weidai11/cryptopp/issues/1231). We added self tests to detect the failures, and cleared the failures.

The new tests also revealed HIGHT/CTR mode also has problems.

--- end body ---

The issue indicates that the HIGHT/CTR mode in the Crypto++ library is producing incorrect results, which could lead to cryptographic failures. However, the description does not provide enough detail to confirm a specific security vulnerability, such as a potential for data leakage or exploitation. It appears to be a bug related to functionality rather than a direct security risk.
