Allow Wave Number as Optional Field in Pick Confirmation REST API

We've made the Wave Number (wavenbr) field an optional (non-mandatory) in the pick_pack/pick confirm API, so you can now pack allocations without needing a wave number.

To do this, simply send a pickpack/pickconfirm API request, without the 'wavenbr' field blank in the body.
