is it heavy or light? I would've thought its light operation given that it's just doing a sha3-512 over the input and all the other hash opcodes are light.

I changed it to light and copied gas_per_unit
from s256
which should be quite similar.

Probably just an oversight. Brandon was wonderin which one it should be, and changing it seemed to make sense. #795 (comment)

The PR originially included changes from an old version of the Blob TX PR. Git merged this part incorrectly and I missed it when reviewing the code myself. Removed in 1c56802.

I re-reviewed myself as well to make sure nothing else was missed.

I feel like the name should mention that we should expect it to "overflow". All of these tests have to do with the offset causing the overflow, so maybe the name should reflect that.
The test_case
names don't really inform me that much either, but I think that has more to do with the base name not being clear enough.

The other tests were named like this as well, I was trying to be consistent. But I just fixed them all in eb11817 now.
