Printing the result of hxToBytes will hang the runtime

```haxe
class Main {
static function main() {
var buf = js.node.Buffer.from('foo');
var bytes = buf.hxToBytes();
trace(bytes);
}
}
```

Run the above code with node 12+, it will hang forever.
node 10 or below is fine though.

However, when run with a debugger (vscode), it will crash with the following error.

```
Waiting for the debugger to disconnect...
internal/util/inspect.js:1249
throw err;

SyntaxError: Invalid regular expression: /(.{2})/: Stack overflow

It could be fixed by commentting out a line in the gennerated js:

```js
js_node_buffer__$Buffer_Helper.bytesOfBuffer = function(b) {
var o = Object.create(haxe_io_Bytes.prototype);
o.length = b.byteLength;
// o.b = b; <-- commentting this line will fix the hang
b.bufferValue = b;
b.hxBytes = o;
b.bytes = b;
return o;
};
```
