42807: Test Orchid Touched
Used by the routine at HandlerOrchid.
Tests whether the player is touching an orchid which is fully grown. If so then the orchid shrinks away (its timer is zeroed), the effect timer in OrchidEffectTimer is started and the player takes on the colour of the orchid. If the orchid is white (71) then the effect timer is reset instead, which removes any effect. A low tone is played.
