This is just the simplest way to move forward implementing the traits of
the lite package. There are alternatives:
We do not want a create a circular dependency between lite and
tendermint (which does not even compile). To avoid this we could:
1) make lite a module of tendermint, or, 2) replicate a lot of the types
of the tendermint crate in the lite package (e.g. Time, Ids etc), or 3)
have a dependency from tendermint to the lite package only (but then the
trait impls do need to live in the lite crate instead with the types in
the tendermint crate directly).
