This adds the best HD=4 CRC32 polynomial. The discovery
is the result of research by Philip Koopman of Carnegie
Mellon University, and is well documented at
https://users.ece.cmu.edu/~koopman/crc/.
The user is given the option of trading 1024B of RAM to
improve the execution speed. The unit tests are parameterized
with this KConfig option.

This commit introduces the `crc8_rohc` function to the CRC library,
implementing the CRC-8/ROHC (RObust Header Compression) variant.
This algorithm is widely used in networking protocols, which is commonly
found in modem subsystems.

Added CRC4 and CRC4_TI to the supported crc_types[] array.
On some SoCs, like ESP32-S3, missing values can cause hardfaults
due to attempts to access the zero address.
