Description

**Is your feature request related to a problem? Please describe.**
The cipher PRESENT cipher is missing. This is not super popular (yet at least) but we've seen it use in ransomware.

**Describe the solution you'd like**
Please consider adding support for these ciphers

**Describe alternatives you've considered**
Using other tools or creating custom one off decoders is the current workaround

**Additional context**

Research direction

Start by reading the linked PRESENT cipher specification and reviewing how CyberChef currently represents supported ciphers. No source file, test, or entry point is named in the issue, so the implementation location and testing approach need to be discovered. Done means CyberChef supports the requested PRESENT cipher instead of requiring custom decoders.
