Improves select_recipe. (#8141)

Browse Source 
* select_recipe improvement

Removes the call to Timsort and the recipe comparator proc;
uses a handrolled implementation of
`argmax(items + reagents + fruit)` instead.
This reduces the memory footprint of `select_recipe`
as well as the amount of processing needed to select the optimal recipe.
