add mode sm3crypt -m 35100

[cyclone-github]

Add sm3crypt (hashcat -m 35100) support.

Implementation follows the upstream libxcrypt v4.5.0 SM3crypt implementation for Unix $sm3$ hashes.

• SM3 digest using github.com/emmansun/gmsm/sm3
• 5000 default rounds
• 16 character crypt-base64 salt
• libxcrypt compatible P/S byte sequences and mixing rounds
• libxcrypt compatible 43 character digest encoding

hashgen usage: -m sm3crypt or -m 35100

Example:

$ echo "hashgen" | hashgen -m sm3crypt
