math: Rewrite vector math library to use packed f64 bytevectors.

The big consequence of this change to the rest of the codebase is that
we can no longer use record destructuring when pattern matching, so I
had to rewrite every place where pattern matching was used.  It was
probably a bad idea to expose the record type descriptors publicly in
the first place.

* sly/math/vector.scm: Reimplement everything in terms of an f64 packed
  bytevector record type.  Do not expose record type descriptors.
* sly/game.scm (run-game-loop): Convert viewport width/height to exact
  numbers.
* sly/window.scm (open-window): Likewise.
* sly/input/mouse.scm (mouse-position): Rewrite pattern matching.
* sly/math/quaternion (make-quaternion, vector->quaternion): Likewise.
* sly/math/rect.scm (rect-clamp): Likewise.
* sly/math/transform.scm (translate!, translate, scale): Likewise.
* sly/render/mesh.scm (vertices-bytevector): Likewise.
* examples/mines/mines.scm: Likewise.
