Overview
Adds a hint for the re-execution of optimistic blocks. In the interop proof, during consolidation, this is required to be able to actually fetch the preimages for the optimistic blocks in the reorg case (i.e., where the original L2 block derived from L1 was reorg'd out due to invalid dependencies.)
This method is a bit of a hack, and we're starting to feel the pain of
kona-driver
's lack of versatility here. The refactor of that crate is tracked in #914, and I'd like to get to that soon, but it's not necessary for this to work. This is much better than the alternative, though, and we can get rid ofkona-providers-alloy
once again.
