EquirectHdrInfoUniform use worker but not disposed in dispose

[dongho-shin]

I tried to test this pr(pmndrs/react-postprocessing#211) for test in react-postprocessing

I found when SSGIEffect instance created, Javascript VM instance has added so I think it is kind of workers but I can't find where the worker created in chrome Mac OS

oh I found it...
https://github.com/0beqz/realism-effects/blob/main/src/ssgi/utils/EquirectHdrInfoUniform.js

updateFrom(map) {
		map = map.clone()
		const { width, height, data } = map.image
		const { type } = map

		this.size.set(width, height)

		return new Promise(resolve => {
			this.worker?.terminate()

			this.worker = new Worker(workerUrl)

			this.worker.postMessage({ width, height, isFloatType: type === FloatType, flipY: map.flipY, data })
			this.worker.onmessage = ({ data: { data, totalSumValue, marginalDataArray, conditionalDataArray } }) => {
				this.dispose()

I think function dispose in EquirectHdrInfoUniform should terminate workers I'll make a PR for this

	dispose() {
		this.marginalWeights.dispose()
		this.conditionalWeights.dispose()
		this.map.dispose()
	}

Oh thanks for seeing that, it can indeed be problematic for memory.
I should fix that before releasing the new version.
