''' State of a picking depends on the state of its related stock.move
- Draft: only used for "planned pickings"
- Waiting: if the picking is not ready to be sent so if
- (a) no quantity could be reserved at all or if
- (b) some quantities could be reserved and the shipping policy is "deliver all at once"
- Waiting another move: if the picking is waiting for another move
- Ready: if the picking is ready to be sent so if:
- (a) all quantities are reserved or if
- (b) some quantities could be reserved and the shipping policy is "as soon as possible"
- (c) it's an incoming picking
- Done: if the picking is done.
- Cancelled: if the picking is cancelled
