An End User would like a composite with an RSA-4096 component algorithm

[johngray-dev]

An end user wants us to add a 4096 bit composite combination:

My reading of the specs matches like this: https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-57pt1r5.pdf

112 bits of security RSA 2048
128 bits of security RSA 3072 ML-DSA-44 192 bits of security RSA 7680 ML-DSA-65 256 bits of security RSA-15360 ML-DSA-87

So we can either switch the RSA-3072 ones to 4096 or add new composite combinations with RSA-4096

@johngray-dev : duplicate of #24 ?

[opencrypto]

Shall this be handled with the IANA registry for the combinations?

Closing issue as it was resolved in Pull #51
