What is the required patch for isar.g.dart?

[jwinarske]

Required changes to lib/isar.g.dart in order to build: final object = TestEntityPlain(); to final object = TestEntityPlain.forIsar(); final object = TestEntityIndexed(); to final object = TestEntityIndexed.forIsar(); final object = RelTargetEntity(); to final object = RelTargetEntity.forIsar();

@jwinarske This is also documented in the README. (But once updated to the current isar release, this should no longer be necessary.)
