Zoroark and Zoroark-Hisui automatically fill their level as being Level 0 for all legal generations

[MaplePokehacking]

This gives incorrect calculations as if the pokemon were level 100 as well as misleading the player on speed tiers and hp thresholds

This explanation by Smogon user A_Wild_Noob_Appeared! explains why Zoroark appears as level 0 in the calc.

[AustinXII]

This makes sense but we probably should have some default level other than 0
