BATTLE.BIN : Check if Status Should/Can be Added
------------------------------------------------------------------------------------------
Parameters - r4 : Clockticks left before Acting Unit next turn
             r5 : Considered Unit data pointer (potential target)
             r6 : Status ID

Returns r2 : 0x00 if status not inflicted yet
             0x00 if status is inflicted but will fade before next turn
             0x00 if considered unit is jumping and will land before next turn
             0x01 if Unit is Jumping and will land later
             0x01 if considered status is innate
             0x01 if considered status is inflicted do not have a CT
             0x01 if considered status is inflicted but won't fade before next turn
 --> r2 = 0x00 if worth to be inflicted
