EquirectHdrInfoUniform use worker but not disposed in dispose

[dongho-shin]

I tried to test this pr(https://github.com/pmndrs/react-postprocessing/pull/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.
