Missing support for parameter sets that use SHA256/192 hashes from draft-fluhrer-lms-more-parm-sets

[ymoyal1]

NIST.SP.800-208 and draft-fluhrer-lms-more-parm-sets/ define extra parameter set for LMS and HSS algorithms.

Support for these parameter sets was added to https://github.com/cisco/hash-sigs/tree/192 also.

The issue is asking to add the support to liboqs as well.

We'd be happy to have them. Would you consider submitting a pull request with the code?

[ymoyal1]

no unfortunately i won't be able to submit a pull request with the code.

Understood. I'll label it as "help wanted" in case someone else is browsing for an issue they can help with.
