Drop support for 1.12 and less. Stick to 1.0.27 to get 1.12 support.
Old selector parameters from 1.12- do not work anymore.
Selectors are now exactly those from vanilla commands, so the following parameters are now working :
• sort=
• nbt=
• advancements=
• predicate=
An error is thrown with more informations when a selector is malformed.
