Create Triplet Interface

[bjornstar]

• Added a Triplet interface to use instead of number[] for improved type accuracy
• Added type safety to the args property
• The args property is now required for two components: ConvexPolyhedron & Trimesh

I can update the docs if you're happy with the changes.

could you make it a named triplet? [number: x, number: y, number: z] ? then we get better IDE context

Sure, already done.

Also added names for some of the args:

type CylinderArgs = [radiusTop: number, radiusBottom: number, height: number, numSegments: number]
type TrimeshArgs = [vertices: (THREE.Vector3 | Triplet)[], indices: Triplet[]]
type HeightfieldArgs = [
  data: number[],
  options: { minValue?: number; maxValue?: number; elementSize?: number },
]
type ConvexPolyhedronArgs = [
  vertices: (THREE.Vector3 | Triplet)[],
  faces: number[],
  normals: (THREE.Vector3 | Triplet)[],
]

nice, could you add it to the docs and then lets merge

README has been updated. I tested it out on racing-game, it's nice to have types for the args :)
