429 Too many requests

[CEBATOR]

Started cleaning slack recently from CI bot spam
Once I got over 100 messages I start receiving:
Failed to delete (429 Client Error: Too Many Requests for url: https://slack.com/api/chat.delete?token=<my token>

According to Slak's Documentation the error shows up once you reach the limit and you should start parsing Retry-After parameter in the response.

you can try to use the --rate 1 to limit the rate of requests to one per second

This actually works!
Thanks!
