Parameterized assembler setup for recipes that need biter eggs.
When biter eggs are added to the requester chest and/or the assembler, a timer starts that is a bit shorter than the hatching time of the eggs. If the timer runs out, a purge is triggered after which everything is reset. Should limit biter breakouts. Replace the active provider with a heating tower for immediate disposal, or (like I do) use a storage chest with egg filter that feeds into a heating tower for mass disposal.
Since the timer depends on using fresh biter eggs, make sure to pull them out of the captive spawners "on demand" by checking the requests on a roboport.
