EBU R128 in WASM

This Package bundles the ebur128 Rust crate as compiled WASM, so it can be used in the browser.

* v1.x.x is compatible with webpack style bundlers
* v2.x.x is compatible for use without bundlers (plain JS/HTML or the old Vite bundler)
* v3.x.x is compatible with the new Vite bundler and webpack

the calls are blocking and take some time to execute, calling this from a WebWorker is advised for best UX.

currently the following methods are exposed:

``ts
/**
* @param {number} sample_rate
* @param {Float32Array} samples
* @returns {number}
*/
export function ebur128_integrated_mono(sample_rate: number, samples: Float32Array): number;
/**
* @param {number} sample_rate
* @param {Float32Array} left
* @param {Float32Array} right
* @returns {number}
*/
export function ebur128_integrated_stereo(sample_rate: number, left: Float32Array, right: Float32Array): number;
/**
* @param {number} sample_rate
* @param {Float32Array} samples
* @returns {number}
*/
export function ebur128_true_peak_mono(sample_rate: number, samples: Float32Array): number;
/**
* @param {number} sample_rate
* @param {Float32Array} left
* @param {Float32Array} right
* @returns {Float64Array}
*/
export function ebur128_true_peak_stereo(sample_rate: number, left: Float32Array, right: Float32Array): Float64Array;
`

these methods correspond to the EBU R128 defined Loudness Normalization functions
