* Add @description decorator
* Unify test case naming style
* more clean ups
* Altair tests cleanup
* Clean up Altair and Bellatrix `process_deposit` tests
* Clean up Bellatrix tests
* Clean up Capella tests
* PR feedback from @ralexstokes
* Add comments on the deposit fork version tests
* Remove `test_incorrect_sig_other_version` since it is duplicate to `test_ineffective_deposit_with_bad_fork_version`
* Add `test_ineffective_deposit_with_current_fork_version`
Introduce `block_to_light_client_header` helper function to enable
future forks to override it with additional info (e.g., execution),
without having to change the general light client logic.
Likewise, update existing light client data creation flow to use
`block_to_light_client_header` and default-initialize empty fields.
Furthermore, generalize `create_update` helper to streamline test code
using `block_to_light_client_header`.
Note: In Altair spec, LC header is the same as `BeaconBlockHeader`.
however; future forks will extend it with more information.
* EIP4844: bytes_to_bls_field() must not accept values >= BLS_MODULUS
bytes_to_bls_field() will be used in the precompile and hence it should error out when provided with malicious inputs.
* EIP4844: Add hash_to_bls_field() for use in compute_challenges()
The previous commit made bytes_to_bls_field() be strict about its inputs. However in compute_challenges() we are
dealing with Fiat-Shamir and hash outputs that could be innocuously higher than the modulus. For this reason we add the
hash_to_bls_field() helper for use in compute_challenges().
* EIP4844: Further use of bytes_to_bls_field() // Fix executable spec

Additionally, it makes the Fiat-Shamir hashing logic more robust by making the challenges independent of each other. It also makes it more efficient to implement by moving both challenge computations to a single function needing a single transcript hash.
