Add populate from requisition functionality to inbound shipment

[josh-griffin]

• in mSupply there's a button Add items from requisition. It does this: https://github.com/sussol/msupply/blob/master/Project/Sources/TableForms/10/input_supplier_trans/ObjectMethods/objAddReqItemsButton.4dm
• I assume we should be doing it? Though if not, great.

I imagine an api mutation, or potentially a query for the requisition to populate from and then to insert client side so that you can cancel out of the operation. Either or, the API is I believe, far away from being able to implement this
