Add support for start time for YouTube videos

[bfintal]

in YouTube videos, you can specify the start time with a t=<time> param, e.g. t=60. It would be great if this can be supported

You should be able to use the iframeSrc option to accomplish this. Here's a wrapper function that should let you add any parameters you want:

const BigPictureExtraParams = ({ el, ytSrc, params }) =>
	BigPicture({
		el,
		iframeSrc: `https://www.youtube.com/embed/${ytSrc}?rel=0&playsinline=1&autoplay=1&${params}`,
	})

// start the video at 25 seconds
BigPictureExtraParams({
	el: e.target,
	ytSrc: 'Crzwq4CjhvA',
	params: 'start=25',
})
