Firebase Realtime Database Wrapper

A basic abstraction over the Firebase Web API.

To begin, create a Database struct by passing the path to your service account token file, and your project id"

```rs use firebaserealtimedatabase::Database;

let database = Database::from_path("project-id", "path/to/token/file.json").await?; ```

The database exposes four methods to interact with the database ```rs let get_result = database.get("users/tom").await?;

let putresult = database .put( "users/joe", &HashMap::from([("firstname", "Joe"), ("last_name", "Mama")]), ) .await?;

let updateresult = database .update("users/joe", &HashMap::from([("lastname", "Ma'ma")])) .await?;

let delete_result = database.delete("users/joe2").await?; ```

Where each method takes a path. Put, Update and Delete take in Serializable data. All methods return a result of reqwest::Response and FirebaseError. FirebaseError contains just a message field that contains the error message.
