Details for working with Aptos based chains.
Because Wormhole works with many environments, the Wormhole address format is normalized.
For Aptos based chains, no normalization is needed for standard addresses since they're already 32 bytes.
However, emitter addresses are recorded as a uint64 (8 bytes), so they're left padded with
0s to 32 bytes.
On Aptos, an emitter capability is taken from the core bridge. The core bridge generates capabilities in a sequence and the capability object ID is its index in the sequence.
The capability object ID (uint64) is used as the emitter address after normalizing to wormhole address format.
This field is may be ignored since the chain provides instant finality.
