Consider unknown machines when deciding to start an order

[snoato]

Currently, we do not consider whether we know all machines required to produce an order when deciding to start work on an order. This can lead us to start orders that are practically infeasible to be delivered in-time (e.g. we do not find all necessary
machines during the exploration phase and the delivery deadline is <4m).

One possible solution would be to consider estimated production times during the order selection and adapt those estimates
to include some representation of the uncertainty of unknown machines (e.g. additional timing, etc.)
