IBC tm client verifying validator voting power

[colin-axner]

Summary

There's an issue on hermes which resulted in a panic from the difference of a validator voting power (total voting power?) in the header and the computed voting power:

Message:  called `Result::unwrap()` on an `Err` value: Error(Context { kind: TryFromProtobuf, source: Some(
   0: tendermint error
   1: invalid raw header
   2: mismatch between raw voting power (0) and computed one (39109268)
Location:

Is this something we should be verifying in client updates? Is this something we should push tendermint to check?
