Provides options to make ytdl-sub look more 'human-like' to protect from throttling. For range-based values, a random number will be chosen within the range to avoid sleeps looking scripted.
Usage:
```
throttle_protection:
sleep_per_download_s:
min: 2.2
max: 10.8
sleep_per_subscription_s:
min: 9.0
max: 14.1
max_downloads_per_subscription:
min: 10
max: 36
subscription_download_probability: 1.0
```
