Add da-avail feature flag (#1433)

* Add data_availibility directory

* move files around and change paths

* rename and move decode_blob

* unpub barycentric

* move eip4844 files into data_availability/

* export functions and structs only

* move get_bytes to decoder

* Add BlobConsistencyWitness and BlobConsistencyConfig

* don't export get_versioned_hash

* cleanup

* Move blob_data up to data_availability

* fix backwards compatibility

* fix rebase

* fix warnings

* remove empty file

* add and use blob_crts_limbs function

* add blob_crts_limbs to AssignedBlobDataExport

* move link out of blob data circuit into aggregation circuit

* remove unused arguments

* unpub get_coefficients

* rename data_availability to blob_consistency

* remove da-eip4844 feature flag

* define N_DATA_BYTES_PER_COEFFICIENT once

* fix da-avail build

* fix typos

* allow dead code for now

* cleanup comments

* Don't use BlobConsistencyWitness in BatchHeader

* don't derive (De)serialize

* add conversion functions

* cleanup

* fix da-avail build

* fix clippy
