Shorthand option -h is used both for help and height

[Yvee1]

Hello,

I noticed running stack exec sketch-exe -- -h gives The option '-h' expects an argument. This is because -h is shorthand for --height, but at the same time also for --help. This is possible perhaps, by using -h without argument for --help and with an argument for --height. In any case, the implementation does not allow that currently.
