An ES6 spec-compliant `ArrayBuffer.prototype.transferToFixedLength` shim. Invoke its "shim" method to shim ArrayBuffer.prototype.transferToFixedLength if it is unavailable.

This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES5-supported environment and complies with the proposed [spec](https://tc39.es/proposal-arraybuffer-transfer/#sec-get-arraybuffer.prototype.transfertofixedlength).

Most common usage:
```js
var assert = require('assert');
var transferToFixedLength = require('arraybuffer.prototype.transfertofixedlength');
var IsDetachedBuffer = require('es-abstract/2023/IsDetachedBuffer');

var ab = new ArrayBuffer('a');

assert.equal(IsDetachedBuffer(ab), false);
transferToFixedLength(ab);
assert.equal(IsDetachedBuffer(ab), true);

if (!ArrayBuffer.prototype.transferToFixedLength) {
	transferToFixedLength.shim();
}

var ab2 = new ArrayBuffer('a');
assert.equal(IsDetachedBuffer(ab2), false);
ab2.transferToFixedLength();
assert.equal(IsDetachedBuffer(ab2), true);
```

## Tests
