feat!: canvas is now an optional peer dependency and not required for operation
feat: add low-level drawBuffer method which is used by drawCanvas and can also be called directly
feat: drawKey and drawScreen now accept either a (RGB16-565) Buffer as the second argument, or a callback. If a callback is used without installing canvas, the user will be informed to install it.
