R6 objects serialized with qs2::qs_save() retain the method bindings from
the class version at save time. After a package upgrade that adds new methods
or fields, qs2::qs_read() returns a stale object. This function reads the
file, then copies all public fields into a fresh TTEPlan instance so that
new methods are available.
Value
A TTEPlan object with the current class definition.
