Key action icons
It would be nice to have icons for performing specific actions with a controller button.

This is Steam Input's list of which actions on a button or stick can activate a control, which I figured would be a good starting point:
1. Regular press
2. Double press
3. Long press
4. Start of press
5. Release of press
6. Analog range
7. Soft press
8. Button chord

Presumably, 1 can just be expressed as the lack of an action icon - but I also figured that having something that explicitly says "just tap, don't do anything else" could be neat, so I made it.

2 through 5 are also present below.

6 and 7 could possibly see a use on joysticks and triggers, but I didn't feel a need to make glyphs for those.

And 8 can just be expressed by a + between two buttons. You don't need anything special for it.

With that said, I've created glyphs for 1-5 as seen below:
![Glyphs for single tap, double tap, long tap, start tap, and end tap](https://github.com/Shinmera/promptfont/assets/1627071/a6bf1835-7a33-4bdf-9736-86aea4905395)

Notably, single and long tap aren't quite centered in the document, but I went for consistency of the button's location compared to the other glyphs in this set for those two.
