[Feature] Add iterator to BlobTransactionSidecar

[mattsse]

Component

consensus, eips, genesis

Describe the feature you would like

this type is a container type

alloy/crates/eips/src/eip4844/sidecar.rs

Lines 22 to 33 in 122c4b1

	pub struct BlobTransactionSidecar {
	/// The blob data.
	#[cfg_attr(
	all(debug_assertions, feature = "serde"),
	serde(deserialize_with = "deserialize_blobs")
	)]
	pub blobs: Vec<Blob>,
	/// The blob commitments.
	pub commitments: Vec<Bytes48>,
	/// The blob proofs.
	pub proofs: Vec<Bytes48>,
	}

all arrays are supposed to have the same length.

an iterator type would be helpful here that yields

struct BlobTransactionSidecarItem {
  index, blob, kzg_commitment, kzg_proof
}

which is basically a subset of

alloy/crates/rpc-types-beacon/src/sidecar.rs

Lines 65 to 75 in 122c4b1

	pub struct BlobData {
	/// Blob index
	#[serde_as(as = "DisplayFromStr")]
	pub index: u64,
	#[serde(deserialize_with = "deserialize_blob")]
	/// Blob data
	pub blob: Box<Blob>,
	/// The blob's commitment
	pub kzg_commitment: Bytes48,
	/// The blob's proof
	pub kzg_proof: Bytes48,

TODO

• introduce type
• add an iterator for BlobTransactionSidecar
• add verify function for BlobTransactionSidecarItem, see also: https://github.com/anton-rs/kona/blob/4ba28121ac0665f268876d6bbf15f1b4dfcbc011/crates/primitives/src/sidecar.rs#L66
