Exponential backoff + do not cache + rename

[anxolin]

1. Adds exponential backoff logic so it can self heal and continue

3. Also renames the script name (to leave it a bit more clear what it is)

4. Adds a new env to avoid to use the CACHE files.

5. Adds an indication of how many tokens left

Test

USE_CACHE=false yarn cowFi:tokens

Now that there's one script in this repo running with TS, would it be too much work to turn these new scripts into TS too?

[alfetopito]
