Is there an option to display in bits instead of bytes?

Yes, there is a `bits` option to display in bits instead of bytes.

According to the README, the `bits` option is a `boolean` with a default value of `false`. When set to `true`, it formats the number as bits instead of bytes, which can be useful when referring to bit rate.

Example usage from the README:
```js
prettyBytes(1337, {bits: true});
//=> '1.34 kbit'
```

In the code, the `bits` option is checked in the main function [index.js:L139-L141] to determine which unit constants to use:

```js
const UNITS = options.bits
	? (options.binary ? BIBIT_UNITS : BIT_UNITS)
	: (options.binary ? BIBYTE_UNITS : BYTE_UNITS);
```

The test file shows various examples, including [test.js:L141-L151] where it demonstrates that values like `1337` with `{bits: true}` produce output like `'1.34 kbit'`.
