[BUG_SP] Grass does not work well

[pops64]

Haven't tested but the way the chopper tells the unload driver which side to be on ignores grass as a fruit. More than likely this will cause the same side to always be selected causing the chopper and its unload driver to face each other every other up/down row. Not to mention breaking drive behind.

Will have to switch this method to using if on a headland track instead of fruit detection. As for up/down rows to be determined. Alternating sides blindly will not work like in 17 as we now have spiral, race track, land and skip row course generation modes which means the next row isn't always the row next to us. Maybe this was solved in 19CP
