Beevee encounter routine

.global beevee_encounter_routine

@the pokemon species gets loaded on 0x080B5012, then calls a function
@for now, beevee's species shall be AB for now, i can change it easily
@r4, r8, and r9 seem to contain the level of the pokemon encountered
@it looks like r1 is disposable at the very beginning, but needs the level before calling the function
@r2 is not used until the function gets called
@r3 contains 118?
@function that gets called is at 0x080B4E68
@beevee table is the species number, and then it ends with 00 00.
