Malfeasance V2

[fasmat]

Description

With ATX v2 new and more efficient malfeasance proofs are needed. Additionally the publisher and handler for malfeasance proofs needs to be updated to be more flexible/generic in handling proofs.

Malfeasance proofs

There are new malfeasance proofs required for checking the contextual validity of a merged ATX

	malfeasance proof	tracking issue
1a.	A PoST included in an ATX is invalid	✅ spacemeshos/go-spacemesh#6141
1b.	same as above, but for v1 initial ATXs	✅ spacemeshos/go-spacemesh#6433
2.	ATXs by an identity form one single chain without branches	✅ spacemeshos/go-spacemesh#6309
3.	ID already married (same node ID in multiple marriage certificates)	✅ spacemeshos/go-spacemesh#6218
4.	two ATXs referencing the same marriage certificate in the same epoch	✅ spacemeshos/go-spacemesh#6335

Malfeasance publisher and handler
