FNet: created "fnet2" protocol

[tasosbit]

Hardcoding the current future protocol as fnet2. This upgrade gates the new fields under the block opcode that were released with 3.26, which were not supported on the binary we released with the original fnet1 support.

Experimental / Not to be merged to main - The target branch dev/experimental-incentives is meant to facilitate FNet users who may want to build from source.

I was discussing current fnet activities with Patrick, and concluded that you probably want to turn off challenges until we have the heartbeat mechanism, or else you'll have accounts inexplicably suspended periodically.

Set Payouts.ChallengeInterval = 0

turn off challenges

Will do but as a separate upgrade, as fnet2 has already been voted through and is scheduled to take effect on FNet in ~2 hours
