Description

Hi,

I'd like to request a short break between search API requests that return 0 images while processing on tag lists. While surfing on Pixiv, I've observed that the site is temp banning the IP if there are too many API requests at once which may be caused by long tag lists and a narrow start and end date time frame.

Same happens if I run a second instance, and the first instance processes empty search API returns. If I don't intervene and pause the script, it's possible to have the IP temp banned.

I think it would suffice to reuse the downloadDelay value in the config.ini.

Steps to Reproduce

1. [First Step]
2. [Second Step]
3. [and so on...]

Expected behavior:

Just a short timeout before the next request, either download or next search API request.

Actual behavior:

PU continues with zero delay.

Hi,

sorry, I couldn't test it earlier. Works perfectly for me with the current code.

Thank you.
