- ability to extract a tipset range into individual vectors.
- ability to extract a tipset range and squash into a single multi-tipset vector.
- mark statediff output deterministically, so it can be extracted by tooling.
- ability to execute callbacks between tipsets in the driver.
- implement save-balances callback.
Unfortunately ChainGetMessage returns a *types.Message, which in
the case of secp messages is lacking the signature. The signature
is part of the input to calculate the CID on secp messages. Therefore,
calling `.Cid()` on the result of ChainGetMessage for this kind of
message will lead to an incorrect CID.
tvx was relying on that call to return the correct CID. Since this is
not the case (and this is a footgun that needs to be corrected, ideally
together with the *types.{,Signed}Message duality mess), I'm replacing
the comparison.
This PR introduces support for running multiple variants of a vector,
each of which targets a unique protocol version.
tvx tooling has been adapted to produce and parse the new version
of the schema.
