PREVRANDAO Support

[mattdesl]

Describe the Feature

Looking for a way to access PREVRANDAO (the mix of the RANDAO from the previously confirmed block).

This might already exist in the field mixHash (which is not exposed in Ethers last I tried), this field should now be renamed to prevRandao as of the merge.

The goal of this would be to give application and game developers access to a strong verifiable PRNG.

Yep it makes sense to include it in the Block interface. cc: @ricmoo

If you are looking for a temp work-around:

const block = await provider.send('eth_getBlockByNumber', [ethers.utils.hexValue(15581032), false])
block.mixHash // "0x1d5c6617045ff0d163123b8dbc0f4c55f91057139973def38ec0e1164f215c04"

@ricmoo
Was this added by any chance? Can't find a way to get PREVRANDAO yet

Thanks for the bump. I have a minor bump going out this week and will investigate this. :)
