/**
Get a Gravatar image from an identifier, such as an email.

@param identifier - The identifier for which to get the Gravatar image. This will typically be an email matching a Gravatar profile, but can technically be any string. The Gravatar service only sees a hash of the identifier, so you could actually use this to get pseudo-random avatars for any entity, e.g. based on its ID. Note that if the identifier contains an `@`, it is assumed to be an email, and will therefore be lower-cased and trimmed before hashing, as per the Gravatar instructions - otherwise it will be hashed as-is.

@example
```
import fs from 'node:fs/promises';
import getGravatar from 'get-gravatar';

const image = await getGravatar('sindresorhus@gmail.com', {size: 200});
await fs.writeFile('sindre.png', image);

console.log('Successfully downloaded the Gravatar image');
```
