Make "show player marker on map" a new prospect difficulty option

The player marker is really helpful. But when you know the map well, you can manage without (with some additional risk to get lost, detour, get into trouble, ...). It would be interesting to choose this risk at the beginning of a prospect (for an additional bonus). So I propose to add a new checkbox "hide player marker" to the "new prospect" dialog. If enabled, the prospect bonus should rise. The lore behind the checkbox could be that providing the player marker requires investment from the contract operator (the company) since they need to task a satellite to watch and track the player.
