Randomize Rainbow Bridge & LACS Requirement Quantity

[Nicholas-Steel]

Suggestion regarding Rainbow Bridge and Light Arrow Cutscene requirements:

When choosing a goal where a quantity can be specified, allow Random Quantity to be an option with the ability to define a minimum and maximum range.

Additionally, when Random Goal is chosen, have a tick box to randomize the quantity of the goal that's randomly chosen. Since the goal can be medallions, spiritual stones, skulltula tokens etc. it would be infeasible to allow setting a minimum/maximum range.
