feat: added option for sprites to be imported as a separate texture

[chqs-git]

Changed the LoadSpriteOpt interface to include the singular boolean. If this values is equal to true the sprite will be loaded as an separate texture, instead of being placed inside a texture sheet where multiple sprites are placed for optimization on texture loads.

These changes should in no way change the default behaviour.

Preview of changes:

loadSprite(
  "player",
  "sprites/player.png",
  {
    singular: true
  }
);

This pull request is for the v4000 version of kaplay because its closer to a feature rather than a fix. If you think this should be included in the v3001 version please comment.
