The asset ID enforced for the next asset creation, if any present. Otherwise, this storage item has no effect.

This can be useful for setting up constraints for IDs of the new assets. For example, by providing an initial [NextAssetId] and using the [crate::AutoIncAssetId] callback, an auto-increment model can be applied to all new asset IDs.

The initial next asset ID can be set using the [GenesisConfig] or the SetNextAssetId migration.
