Create FRP-6: Assesing Flashbots Alpha's MEV extraction

[Alejo Salles]

FRP-1 is being partitioned into more manageable chunks #22. FRP-6 will assess how far the current Flashbots Alpha is along the path to optimal extraction. A proposal needs to be written.

Prior notes taken with @sbaks0820:
FRP-6: Where is the current POC and what is the "ideal" implementation we are going towards?
Are the differences between POC and "ideal" large enough that they require different auction designs? Why and does what auction they need determine which implementation is the better one? --> is one of them more "good" (define!) than the other
Right now(?): sells the ordering of the entire blocks
Ideal (?): to be able to sell block space before/after oracle updates and small tx bundles (2,3,4 txs in a specific ordering)
IMPORTANT add to MEV research the current spec/auction mechanism in use in the POC.
