Feature request: TEA & XTEA Ciphers

**Is your feature request related to a problem? Please describe.**
The ciphers TEA and XTEA are missing, cyberchef current supports XXTEA as of recently, but note this is distinct from TEA and XTEA.

**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**
TEA: https://en.wikipedia.org/wiki/Tiny_Encryption_Algorithm
XTEA: https://en.wikipedia.org/wiki/XTEA
XXTEA: https://en.wikipedia.org/wiki/XXTEA

Start by locating CyberChef's existing XXTEA support and its related tests or operation entry point. Compare the TEA and XTEA references linked in the issue with the existing cipher implementation, then verify that both ciphers are available and tested alongside XXTEA.
