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.
