new branch that makes initial commit to ruse aws_lc_rs instead of openssl. This make the dependency simpler. This is a initial commit that tries to make a rewrite of existing functionality. md5 and des were not ported to this feature as they cannot be done within aws_lc_rs.

Important notes:

• I have done it as a simple rewrite - no design decisions or anything like it I just tried to replicate functionality 1:1
• I am not cryptography expert nor snmp expert. I think I was able to make this PR as a starting point proof of concept.
• No MD5 and DES as they are not in aws_lc_rs. Also if I understand correctly I cannot have them If we want fips. It can be added but with other dependencies
• I did use Claude Opus 4.5 to help myself make the work faster.
• It was not vibe coded - I reviewed everything and tested this with my program that uses this repo code after changes
