/**
* The inbuilt toEqual() matcher will always return TRUE when provided with 2 ArrayBuffers.
* This is because an ArrayBuffer must be wrapped in a new Uint8Array to be accessible.
* This custom matcher will automatically instantiate a new Uint8Array on the received value
* (and optionally, the expected value) and then call toEqual() on the resulting Uint8Arrays.
