Bug: ImageProps.sizing w, h, x, y are typed number but should be Coord

Version

Please specify what version of the library you are using: [ 3.10 ]
Please specify what version(s) of PowerPoint you are targeting: [ any ]

Expected / Desired Behavior / Question

When the sizing properties of ImageProps are specified as a percentage of the slide dimensions, the code should compile in Typescript, because it works at runtime:

new pptxgen().addSlide().addImage({
	data: imgData,
	sizing: {
		type: "contain", 
		w: "90%",
		h: "75%",
		x: "5%",
		y: "20%"
	}
});

sizing w, h, x, y should be typed Coord, the same as PositionProps and others.

Observed Behavior

Typescript reports error "Type 'string' is not assignable to type 'number'." because those four properties are all typed number.

Steps to Reproduce

Type the above into VS Code.

I will submit a pull request.

In addition, instead of

export type Coord = number | string

the Coord type could be further constrained using a template literal:

export type Coord = number | `${number}%`

Thanks for the issue and patch @BistroStu !

Also, i've never seen ${number}% used in lieu of string before - appreciate the new found syntax. :-)

${number}% provides an error while TS compilation. "TS2693: Number only refers to a type, but is being used as a value here."

I'm using TS 3.9.7
