* Reuses move parse result objects for each encounter parsed in a LegalityCheck attempt, instead of creating a new object.
* Ensures the objects are never-null, and makes cleanup easier.
Slightly adjusts some other parts of the moveset validation to reduce allocations.
Looks like Mr. Rime case wasn't being handled, so I rewrote it. Better performance, less complexity. No need to double-reference the moves.
Cache a single Valid evolution result; every parse can reuse that object.
Check successive move slots after the current index rather than doing a count eq >= 2.
Flag all empty slots prior to a filled move slot, rather than flagging a full slot as invalid because "empty move".
Was referencing wild caught mons that are given a single egg move; this
logic handles shared egg moves too via daycare.
Probably need to rework SplitBreed into a dictionary; this might not
catch Mime/etc split breeds if they have different tables.
* Add move source to the check result for current moves, it will be used for analysis of evolution with move to determine how many egg moves had the pokemon and determine if the evolution move could be a egg move that was forgotten
* Verify evolution for species that evolved leveling up with an specific move learned, the evolution must be at least one level after the pokemon could legally learn the move or one level after transfer to the first generation where it can evolve
* Check to detect traded unevolved Kadabra based in catch rate and moves exclusive from yellow or red/blue
If pokemon have data exclusive from one version but is in another version that means it should be evolved
* Check no tradeback moves for preevolutions, like Pichu exclusive non tradeback moves for a Pikachu, that Pikachu could not have at the same time Pichu gen 2 moves and gen 1 moves because move reminder do not allow to relearn Pichu moves and gen 2 moves must be forgotten to trade into generation 1 games
* Legallity strings for non tradeback checks

Eggs only inherit a level up move if both parents know the move, that means genderless and male only moves could not have any level up move as an egg except the base egg moves because Ditto is one parent
Nidoran male and Volbeat excluded because they can breed with Nidoran female and Illusime
* Small check to not search for egg moves in genderless pokemon, generation 2 data include egg moves for Starmie
* Fix female only species
* Stomp is not a possible egg moves of Stanee
* Fix Steenee evolution move, it cant be inherited as an egg
