We have renamed most methods to drop the "command" suffix as it is quite redundant. Due to this change and thanks to variadic methods introduced with PHP 5.6 we took the opportunity to replace both "supportsCommand()" and "supportsCommands()" with a single new method "supports()". Added more stringent typehints for method arguments and typehints for return values now that we do not need to support anything below PHP 7.2. Also moved from using array() to [] in source code of class involved.
