test_invalid_blob_gas_used_in_header()

Documentation for tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_invalid_blob_gas_used_in_header@343274cc.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip4844_blobs/test_excess_blob_gas.py::test_invalid_blob_gas_used_in_header --fork Amsterdam

Test rejection of blocks where the blobGasUsed in the header is invalid.

• blobGasUsed is not equal to the number of data blobs in the block
• blobGasUsed is the max uint64 value
