Add support for setting slider height and width

[FerretMonger]

Is your feature request related to a problem? Please describe. I would like to be able to set the height and width of the slider (card). I tried using card-mod but couldn't figure out if it was possible at all or just me being bad at css.

Describe the solution you'd like Two settings. One for Height and one for Width.

I would love this request fulfilled as well. I also couldn't set height via car-mod. Apparently slider-button-card sets a min-height: 3rem !important; as a "constructed stylesheet" which I am not able to override.
