RocketSilo: Prevent automatic launch if there is no space for products

[Earendel]

Request for a setting on the rocket silo prototype to change the "check adequate space in inventory" behaviour from no check to a check that can be enabled by the mod.

For example: rocket_silo.automatic_launch_requires_space_for_product = true/false
(or something like that.)

This relates to this discussion: viewtopic.php?f=23&t=46853 however that discussion is largely focussed on gameplay design decisions for vanilla Factorio, not the role of a rocket silo in a modded context.
