fix: refuse to process unsupported feature

[0xalpharush]

See firedancer-io/solana-conformance#148 for more context.

This doesn't ensure hardcoded features are activated, but it's helpful to validate inputs generated independently of solfuzz

thanks!

I can run the vectors with the script locally, so I'm not sure why CI is failing

The features hitting the panic I introduced are marked as unsupported in solfuzz-agave enable_big_mod_exp_syscall, zk_token_sdk_enabled, remaining_compute_units_syscall_enabled with comments indicating FD does not support them.

Should the features not be activated in the test-vectors or just not enabled for fuzzing?
