This nim-web3 bump isn't safe: #3850

That's an issue in nim-web3, and I'll revert the changes there. This Quantity thing is a real spec divergence, but also, shouldn't block other things in the meantime.

Also, because of the other spec ambiguities detailed there, already reported, it's not clear exactly what "correct" handling of the "Quantity" difficulty/totalDifficulty would be, so it can't be made unambiguously correct, pending JSON-RPC clarifications.

None of which is directly relevant here, just, why the fix isn't just-add-one-more-change-to-ethtypes instead of revert.

[tersec]

It shouldn't need a full revert -- there's one specific condition which causes problems currently due to the somewhat less-than-rigorous Quantity usage (e.g., for various hashes which are definitely not defined as integer quantities, too): status-im/nim-web3#55

this import is quite unfortunate: it brings in the entirerty of web3 which transitively imports lots and lots of completely irrelevant stuff just to get access to a trivial byte converter
