Nimbus t8n 4844 support

[winsvega]

as nimbus now is getting the best t8n implementation
to make tests around 4844 it would be good to have blob tx support.

in t8n reponse file
"currentExcessDataGas"
in env t8n file
"parentExcessDataGas" (to calculate the formula) or "currentExcessDataGas" (to set the value without formula)

Hai @winsvega , eip-4844 branch is ready for testing. Hope it works well because it's still fresh from the oven

@jangko, found the way to break it.
the code:

[[2]] (BLOBHASH 0xffffffff) ; 32
             [[3]] (BLOBHASH 0xffffffffffffffff)  ; 64
             [[4]] (BLOBHASH 0xffffffffffffffffffffffffffffffff) ; 128
             [[5]] (BLOBHASH 0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff) ; 256

if I pass the high value to BLOBHASH opcode, the evm fails:
Error: IndexDefect : index -1 not in 0 .. 1

@winsvega , BlobHash bug fixed.
