SetUnitWantsERN

SetUnitWantsERN(<-UID, <-wantsERN)

Sets whether the unit with the specified UID desires an ERN. Pass `true` to make the unit desire ERN, or `false` to indicate it does not.

# need worked example

# A unit that has an ERN slotted and receives the 4rpl command to "not want an ERN", 
# will not actually unequip the ERN. As a workaround, it is possible to destroy the unit 
# and recreate it without the ERN. That's what this function is for.
