API Changes:

Added: placeholder registration system
NEW PLATFORM: Added support for Minestom
Fixed: greedy arguments parsing providing the value with extra last space.
Fixed: uppercase commands not correctly being executed.
Refactored: ContextFactory to an abstract class with a constructor parameter of type Imperat<S> ,
while also removing the method parameter Imperat<S> from its abstract methods.
Refactored: the field OptionalValueSupplier in class CommandParameter is now annotated with @NotNull
meaning it can't be null, you can add a null optional value using OptionalValueSupplier#empty(TypeWrap type)
as the method OptionalValueSupplier#getValueType's return type has changed from Class<T> to TypeWrap<T>
Added new methods in AnnotationParser<S>:
- isKnownAnnotation(Class<? extends Annotation> annotationType)
- registerAnnotations(Class<? extends Annotation>... types) (to register custom annotations)
- hasAnnotationReplacerFor(Class<? extends Annotation> type)
- getAnnotationReplacer(Class<A> type)

Internal Changes:

Replaced some internal maps with our Registry class for better and cleaner code.
Added: Registry#update methods
Added: test environment for S.U.R
Refactored: the class AnnotationRegistry to become package-private/internal and inaccessible.
