done but resolve_futures doesn't seem to work properly with LOG_LEVEL=DEBUG. And the executor ratelimit dosen't really work nicely with this source, it does finish eventually with retries tho.

Used this novel for testing with 20 pages/637 chapters.

For LOG_LEVEL=DEBUG, it just does not show the progress bar.

I had trouble scraping from reaperscans before as well. one day it works, the other day requests fail frequently. we can test using different ratelimits for this. e.g. a value of 0.5 might fare better.

I will merge this commit as it is now. If you have found a good ratelimit for reaperscans please make another PR
