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. The function supposes that the unit that has to lose the ERN, is already constructed, which might not always be the case.
