feat: add handle to expose FormattedText of the text component

[dragoncoder047]

this would be useful to get the bounding boxes of the text and see where the user clicked

currently you have to do this if you want to account for everything the text could do to style the characters

const formattedText = formatText({
    text: this.text,
    pos: this.pos,
    scale: this.scale,
    angle: this.angle,
    color: this.color,
    opacity: this.opacity,
    fixed: this.fixed,
    shader: this.shader,
    uniform: this.uniform,
    outline: this.outline,
    font: this.font,
    size: this.textSize,
    align: this.align,
    width: this.width,
    lineSpacing: this.lineSpacing,
    letterSpacing: this.letterSpacing,
    anchor: this.anchor,
    transform: this.textTransform,
    styles: this.textStyles,
});

it can be simplified to

const formattedText = this.formattedText;

it is expensive to compute so at least it would be a getter, maybe a method
