Fix flute level amp direction
The inputs to "IsLevelWithinRange" are the highest value the
lowest-level can be, and the lowest value the highest level can be...
seems confusing (hence the original error).
If a slot is 6-7, with a wild encounter (flute), we can go +/-3 from
6-7, which is 3-10.
With an encounter of level 5, the inputs are: 5+3, and 5-3 (8, 2).
Since 8>lvlmin and 2<lvlhi, we can get a level 5 pkm from the slot
(using a negative flute yielding a -1 adjustment).
I could probably refactor it to be a 3-input signature (lvl, lvlneg,
lvlpos), and have it do LevelMin - lvlneg <= lvl && lvl <= LevelMax +
lvlpos
I should probably refactor these methods to do minLevel & maxLevel (so
baseSpecies.Level to CurrentLevel for pkm that lost their original met
data) but nothing needs the extra logic at this time.
