Add the conan recipe and add intx to conan center.

It seems current intx implementation is not compatible with C++20 `operator `. The test case is something like: ```cpp struct S { intx::uint256 x; operator() = default; } ```

If you consider 256x256 bit division (i.e. 4-by-4 words division) where division by 1 and 2 words is already fast, the Small Quotient Division should nicely apply to remaining 4-by-4...

Performance analysis of DATASET_PARENTS​=512

The [ProgPoW software audit](https://github.com/ethereum-cat-herders/progpow-audit/raw/master/Least%20Authority%20-%20ProgPow%20Algorithm%20Final%20Audit%20Report.pdf) recommend to increase the `DATASET_PARENTS​` Ethash cache parameter from 256 to 512. This has direct impact on verification performance as the time for single verification doubles...

The FNV hash functions are used incorrectly

3

In the original design, each byte of input is treated with a round of the FNV hashing. https://en.wikipedia.org/wiki/Fowler%E2%80%93Noll%E2%80%93Vo_hash_function In Ethash input data is hashed in 32-bit chunks following the FNV-1...

The current implementation is done by bits manipulation on whole 256-bit values (as you would do it for architecture native integers). There exists more efficient implementation which handles each of...
