Fix the processing for constant salt
KNX IP Secure uses a constant salt, which require the use of `OPTS_TYPE_DEEP_COMP_KERNEL`. This commit adds the required options and adjusts the indexing of the esalt accordingly. The attempt at an optimized kernel has been removed as requested in the PR feedback. Additionally, minor formatting improvements have been made.

* This function assumes that the input is a hash of length 256 bit with padding applied and that the total length
|
||||
* of all blocks is 768 bit. This allows to perform optimizations in the message schedule and hash round since some
|
||||
* words are known to be all zero bits, thus not contributing to some of the calculation. Additionally, calculations
|
||||
* for words that are known to be constant have been precomputed.
|
||||
*
|
||||
* The 256 bit hash is located in the first 8 words (index 0 to 7), followed by one word that has one bit set.
|
||||
* The length is represented as a 128 bit integer in the last 4 words. However, since for the HMAC calculation
|
||||
* the total size of all blocks doesn't exceed 768 bit, including ipad and opad respectively, only the last
|
||||
* word (index 15) contains the length bits. Thus the 32 bit words from index 9 to 14 are all zero bits.
|
||||
* Whenever these words would be used by the message schedule in
|
||||
* Wt = SSIG1(W(t-2)) + W(t-7) + SSIG0(W(t-15)) + W(t-16) [1]
|
||||
* or in the hash round in
|
||||
* T1 = h + BSIG1(e) + CH(e,f,g) + Kt + Wt [1]
|
||||
* the calculation can be simplified to remove the operand.
|
||||
*
|
||||
* The word at index 8, with one bit set, and the word at index 15, containing the length, are know to be constant.
|
||||
* Therefore, the operations where they are used as an operand can be partially precomputed. For the message schedule
|
||||
* this is possible for SSIG1(W(t-2)) and SSIG0(W(t-15)). In the hash round the Kt + Wt can be precomputed when Wt
|
||||
* is constant.
|
||||
*
|
||||
* Like sha256_transform_vector it performs the message schedule and hash round calculation jointly for 16 of the
|
||||
* 32 bit words. This requires fewer variables and thus less memory to hold the state, compared to calculating
|
||||
* the whole message schedule first and then performing the hash round.
