Adds a the new field `breaking` to the `date_range` plugin, to toggle whether an entry breaks subsequent metadata pulls. This is useful to disable if you are grabbing a playlist that may have videos out of order, but still want to apply a date range to it.
Adds a new mechanism to limit subscriptions' number of videos to an explicit number (only supported date ranges prior to this).
Example usage:
```
output_options:
keep_max_files: 10
```
will only keep 10 videos at max.
In addition:
- `keep_max_files` is bundled into the `Only Recent` preset and can be used via setting the `only_recent_max_files` override variable (see examples or README for usage).
- Changed the `date_range` variable name to `only_recent_date_range` for more clarity. Usage of `date_range` will continue to work.
A follow-up to the prior commit which fixes some bugs in the 'beautiful subscriptions' implementation. A proper migration guide will be written in the wiki once it's ready
Makes setting yt-dlp's `format` field easier by giving it its own documented plugin.
Old:
```
my_format_preset:
ytdl_options:
format: "best"
```
New:
```
my_format_preset:
format: "best"
```
The old method will still work, so do not worry about updating configs ASAP. However, the option is available to save a few lines 😉
