Splits EncounterEgg into derived classes, allowing for fine-tuned control of each generation's egg generation & pattern matching.
Adds an interface to check if the encounter is a bred egg (useful for many scenarios when checking for move inheritance, in general).
Enhances the deferral rating for PIDIV matches in eggs based on global legality check settings.
Adds date/time indicators for Gen3/4 eggs and other Method 1 encounters.
In addition to the Method 1 (and other sibling PIDIV types) correlation, an encounter can only be triggered if the calls prior land on the Method {1} seed. The RNG community has dubbed these patterns as "Method J" (D/P/Pt), "Method K" (HG/SS), and "Method H" (Gen3, coined by yours truly). The basic gist of these is that they are pre-requisites, like the Shadow locks of Colosseum/XD.
Rename/re-type a bunch of properties to get the codebase more in line with correct property names & more obvious underlying types.
With the new version of Visual Studio bringing C# 12, we can revise our logic for better readability as well as use new methods/APIs introduced in the .NET 8.0 BCL.
