fix: Argument of type 'Uint8Array<ArrayBufferLike>' is not assignable to parameter of type 'Uint8Array<ArrayBuffer>'
/**
* Asserts that the provided Uint8Array is backed by an ArrayBuffer.
*
* Throws an error if the buffer is a SharedArrayBuffer or any other type.
* This is useful for ensuring (type) compatibility with APIs that require Uint8Array<ArrayBuffer>.
* Usage:
* // bytes: Uint8Array<ArrayBufferLike>
* assertArrayBuffer(bytes);
* // bytes: Uint8Array<ArrayBuffer>
