Customizable separator tab for parametric compartment box

A simple customizable separator with tab. I made this a separator for storing cards in a custom box made with the [parametric compartment box with lid](https://www.thingiverse.com/thing:15113).

It includes an optional label and adapts the text's size to the tab size. The label can be either engraved or embossed (e.g. for dual color printing).

Parameters:
* **width**: (mm) Width of the separator.
* **height**: (mm) Height of the separator.
* **tab_height**: (mm) Height of the tab (on top of the separator).
* **tab_width**: (mm) Width of the tab.
* **depth**: (mm) Depth of the separator/tab.
* **print_label**: (bool) Add a label to the tab.
* **carved_label**: (bool) Carved label. Embossed label if false.
* **label**: (text) Text for the label.
* **right_side**: (bool) Place tab on the right side of the separator. On the left if false.
