feat: themes

IMHO, this add-on needs:

1. fire, snow, fast smear, etc. as themes

theme = 'snow',  -- obviously use defaults if missing

2. let people overload them, e.g.

theme = 'moresnow',
themes = {
  moresnow = { extends = 'snow', particle_spread = 3 },
},

3. functions like :SmearCursorTheme <name> and :SmearCursorTheme{Next,Prev}

(optionally) an array of themes to cycle through (cycle all by default)

I think it's better UX than keeping blocks of text in init.lua, and commenting/uncommenting them when you want to show off your editor. And yeah, anyone can code that themselves in Lua, but it'd be nice to have out of the box.
