With both `--match` and `--dl-override`, it is now possible to more easily experiment with subscriptions without needing to create a separate file.
For example, suppose you are changing some values in your subscription "Rick A" and want to test them out. You can now run:
```
ytdl-sub sub --dry-run --match Rick --dl-override '--ytdl-options.max_downloads 3'
```
This will
1. Dry-run
2. Only run for the subscription "Rick A"
3. Apply setting max_downloads to 3
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
```
