Blob transactions are SSZ encoded, so it had to be added to decoding.
There are 2 encoding forms: `network` and `minimal` (usual). Network
encoded blob transactions include "wrapper data" which are `kzgs`,
`blobs` and `proofs`, and decoded by `DecodeWrappedTransaction`. For
previous types of transactions the network encoding is no different.
Execution-payloads / blocks use the minimal encoding of transactions. In
the transaction-pool and local transaction-journal the network encoding
is used.
Concerns:
1. Possible performance reduction caused by these changes, not sure if
streams are better then slices. Go slices in this modifications are
read-only, so they should be referred to the same underlying array and
passed by a reference.
2. If `DecodeWrappedTransaction` and `DecodeTransaction` will create
confusion and should be merged into one function.
Logic to compute fees for data blobs as well as additional check that
verifies if user was willing to pay the current `data_gas` price.
Updated `FakeExponential` function to work with uint256.
This is the beginning of the series of changes to make it possible to
run multiple instances of erigon inside a single process (as devnet tool
does), with the logging from these processes going to respective log
files correctly.
This is the first part where the initial infrastructure is being
established

Update to latest erigon-lib which now has the kzg context and update
crate-crypto to latest.

Transaction extension to support BlobTxWrapper (or network
representation of BlobTx). BlobTxWrapper wraps BlobTx with additional
data: blobs, commitments and proofs. Unwrap() returns unwrapped tx if
its network tx, otherwise returns itself.
types.NewMessage now expects maxFeePerDataGas param, which will be used
in transaction verification (preCheck). GetPayloadV3 method added to
EngineAPI. Some cosmetic changes applied.
In this PR Header's ExcessDataGas is set to the actual value, but it's
still unused. It will be used to compute data fee for eip-4844 data
blobs, logic of which will be added in later PRs. Also eip-4844 header
verification logic added.
`excessDataGas` has been partially made eip-4844 ready, so instead of
passing nils to functions, now it actually assigned to some value (it is
expected to be nil until cancun update).
New transaction type added. This transaction differs from previous
transactions in a network encoding. Network encoding of a new
transaction wraps "regular" transaction with additional data: blobs and
kzgs. The network wrapper will be verified by execution layer using this
extra data.
