v3.1.0

💥 Remove eventpp api to replace it with qobject_cast and signal/lambda.

QOlm provide lambda connection with already qobject_cast objects. This is the preferred and easier way to observe the list

FooList list;

// Preferred API, safer to use when giving a context
list.onInserted(&list, [](Foo* foo, int index){});
list.onInserted(&list, [](Foo* foo){});
list.onRemoved(&list, [](Foo* foo, int index){});
list.onRemoved(&list, [](Foo* foo){});
list.onMoved(&list, [](Foo* foo, int from, int to){});

// Should only be used when your callback doesn't require any context
list.onInserted([](Foo* foo, int index){});
list.onInserted([](Foo* foo){});
list.onRemoved([](Foo* foo, int index){});
list.onRemoved([](Foo* foo){});
list.onMoved([](Foo* foo, int from, int to){});

When connecting without any receiver, this list is used as the context.
