fix(sdk): Return Bytes when using Vec<u8> in params and result

[shekohex]

This pull request includes an improvement to the ValueIntoFieldType implementation in the sdk/src/event_listener/tangle/mod.rs file. The main change is the addition of a type check to handle Vec<u8> more efficiently and safely.

Enhancements to ValueIntoFieldType implementation:

• Added a type check for Vec<u8> in the ValueIntoFieldType implementation to convert it directly to Field::Bytes using Vec::from_raw_parts, ensuring proper memory management and avoiding double-freeing issues.

Note that this a hot-fix, to get myself unblocked in my current task. However this won't be needed once #424 is fully implemented.

Closes #427

What if it's a Vec?

What Vec? you mean anything other than a Vec<u8>? like a Vec<u32> or a Vec<Something>? These are treated as Field::List we have that type for those. Vec<u8> is just treated special because it is bytes.

Looks like if it's not immediately a Vec<u8>, it will call each element's ValueIntoFieldType recursively until it is resolved.
