Public variable for "renderer" has incorrect type definition

[ketz]

In lottie-player.ts, on line 196, "renderer" is defined as type "svg", but that is its default value, not the variable type.
It should be defined as :string

` /**

• Renderer to use.
  */
  @Property({ type: String })
  public renderer: "svg" = "svg";`

The current definition is triggering an error when trying to set the variable dynamically on a new LottiePlayer() object - "Type 'string' is not assignable to type '"svg"'"
