feat: add BLOBHASH and BLOBBASEFEE

[Rjected]

Was trying to disassemble some cancun contracts with cast disassemble and noticed these needed to be added

Thank you for the PR. Changes look good to me.
One question:
What is the authoritative source on the new opcodes to be introduced in Cancun ?
For example it seems that there might also be a "BEACON_ROOT" opcode to be introduced but I couldn't find any info on wether this EIP will actually be part of cancun.

The best way to track which EIPs will be in cancun is to check the devnet spec:
https://notes.ethereum.org/@ethpandaops/dencun-devnet-10

We are also implementing as many as possible in revm:
https://github.com/bluealloy/revm/blob/47b38af503ee9506b48b2cda8e8f06abf6093e14/crates/interpreter/src/instructions/opcode.rs

Also see the new point evaluation precompile in revm:
https://github.com/bluealloy/revm/blob/47b38af503ee9506b48b2cda8e8f06abf6093e14/crates/precompile/src/lib.rs#L204-L227

EIP-4788 is included in cancun, but instead of being a stateful precompile it is now a regular contract.

Thanks, that helps a lot 🙏
