Disassociate pk4/pk6 backing byte[] when converting to pk5|pk7, as we no longer make a copy of the byte[] in the pkm's constructor.
Change UpdatePKM to include isParty, as we want it optional to update FormArgument too.
Change FormArgument saving to be handled by FormConverter; kinda not really good to have it there, but nothing else is handling FormArgument values.
Expand IFormArgument to have all FormArgument values exposed. "Maximum" is furfrou only.
PK6: Max is in the "FormArgument" u32, and the remain/elapsed is in party stats (hence the reverting when boxed)
PK7: u8 remain, u8 elapsed, u8 max, u8 unused.
PK8: assumedly the same as PK7, given the disassembly hints that it's the same as past games (even though Furfrou and Hoopa are not in SWSH).
Update dictionary to use proper format (yyyy-mm-dd), as well as verifier to properly check met year.
Also updated IsValidDateWC8 to clamp latest met date based on UTC, like with GO encounters.
## Issue
We want to discard-but-remember any slots that aren't a perfect fit, on the off chance that a better one exists later in the search space. If there's no better match, then we gotta go with what we got.
## Example:
Wurmple exists in area `X`, and also has a more rare slot for Silcoon, with the same level for both slots.
* We have a Silcoon that we've leveled up a few times.
Was our Silcoon originally a Wurmple, or was it caught as a Silcoon?
* To be sure, we have to check the EC/PID if the Wurmple wouldn't evolve into Cascoon instead.
* We don't want to wholly reject that Wurmple slot, as maybe the Met Level isn't within Silcoon's slot range.

Existing implementation would store "deferred" matches in a list; we only need to keep 1 of these matches around (less allocation!). We also want to differentiate between a "good" deferral and a "bad" deferral; I don't think this is necessary but it's currently used by Mystery Gift matching (implemented for the Eeveelution mystery gifts which matter for evolution moves).
The existing logic didn't use inheritance, and instead had static methods being reused across generations. Quite kludgy. Also, the existing logic was a pain to modify the master encounter yield methods, as one generation's quirks had to not impact all other generations that used the method.
---
The new implementation splits out the encounter yielding methods to be separate for each generation / subset. Now, things don't have to check `WasLink` for Gen7 origin, because Pokémon Link wasn't a thing in Gen7.
---
## Future
Maybe refactoring yielders into "GameCores" that expose yielding behaviors / properties, rather than the static logic. As more generations and side-gamegroups get added (thanks LGPE/GO/GameCube), all this switch stuff gets annoying to maintain instead of just overriding/inheritance.
## Conclusion
This shouldn't impact any legality results negatively; if you notice any regressions, report them! This should reduce false flags where we didn't defer-discard an encounter when we should have (wild area mons being confused with raids).
Closes#3133
not an ideal solution, but the encounter matching API is kinda limited in deferred-invalid vs deferred-notIdeal.
probably need to unify the match logic and generators so they can cache one secondary-check invalid
