Hot Patch

This patch includes a new feature, lots of improvements and a bug fix:

NEW Experimental feature (unstable)

Added flag shorthands parsers using advanced flag extracting algorithms.
e.g: instead of -a -b -c , you can now do -abc. Contact @Mqzn for more details.

NEW: ParameterCompletableFuture , you can automatically add CompletableFuture<T> parameters where you must ensure that there's a parameter type registered for T too.
NEW: ParameterOptional, you can automatically add Optional<T> parameters where you must ensure that there's a parameter type registered for T too. (NOTE: this does NOT specify this argument/parameter as an optional parameter).
Improved performance of auto completion for suggestions.
Added automated type-capturer, so you don't need to specify the class in your ParameterType sub class's constructor,
just implement the method and that's it :D!, special thanks to @iiAhmedYT .

Fixed accumulation of suggestions if there's optional argument,
after auto completing an required argument.
