bannerbear-ruby's Issues

Handle rate limiting internally

What happens:

When calling create_image() too frequently (more than 30 times in 10 seconds), it throws a JSON parse exception from deep inside the gem that contains a Cloudflare html response:

Traceback (most recent call last):

What I expected:

I expected the client library to recognize the retryable 429 response code and take care of pauses and retries as needed.

Or, less ideal, but better: I'd expect to get a JSON response that's parsed correctly by the library instead of an exception.
