Native SponsorBlock implementation and related improvements (#360)

Browse Source 
SponsorBlock options:
* The fetched sponsor sections are written to infojson
* `--sponsorblock-remove` removes specified chapters from file
* `--sponsorblock-mark` marks the specified sponsor sections as chapters
* `--sponsorblock-chapter-title` to specify sponsor chapter template
* `--sponsorblock-api` to use a different API

Related improvements:
* Split `--embed-chapters` from `--embed-metadata`
* Add `--remove-chapters` to remove arbitrary chapters
* Add `--force-keyframes-at-cuts` for more accurate cuts when removing and splitting chapters

Deprecates all `--sponskrub` options

# NEW FEATURES
The major new features from the latest release of [blackjack4494/yt-dlc](https://github.com/blackjack4494/yt-dlc) are:
* **[SponSkrub Integration](#sponskrub-sponsorblock-options)**: You can use [SponSkrub](https://github.com/yt-dlp/SponSkrub) to mark/remove sponsor sections in youtube videos by utilizing the [SponsorBlock](https://sponsor.ajay.app) API
* **[SponsorBlock Integration](#sponsorblock-options)**: You can mark/remove sponsor sections in youtube videos by utilizing the [SponsorBlock](https://sponsor.ajay.app) API
* **[Format Sorting](#sorting-formats)**: The default format sorting options have been changed so that higher resolution and better codecs will be now preferred instead of simply using larger bitrate. Furthermore, you can now specify the sort order using `-S`. This allows for much easier format selection than what is possible by simply using `--format` ([examples](#format-selection-examples))

## SponsorBlock Options:
Make chapter entries for, or remove various segments (sponsor,
introductions, etc.) from downloaded YouTube videos using the

the path to the binary or its containing

--sponsorblock-mark CATS SponsorBlock categories to create chapters
for, separated by commas. Available
categories are all, sponsor, intro, outro,
selfpromo, interaction, preview,
music_offtopic. You can prefix the category
with a "-" to exempt it. See
https://wiki.sponsor.ajay.app/index.php/Segment_Categories
for description of the categories. Eg:
--sponsorblock-query all,-preview
--sponsorblock-remove CATS SponsorBlock categories to be removed from
the video file, separated by commas. If a

"[SponsorBlock]: %(category_names)l"

- `urls` (string): The URLs of all requested formats, one in each line
- `filename` (string): Name of the video file. Note that the actual filename may be different due to post-processing. Use `--exec echo` to get the name after all postprocessing is complete
Available only in `--sponsorblock-chapter-title`:
- `start_time` (numeric): Start time of the chapter in seconds
- `end_time` (numeric): End time of the chapter in seconds
- `categories` (list): The SponsorBlock categories the chapter belongs to
- `category` (string): The smallest SponsorBlock category the chapter belongs to
- `category_names` (list): Friendly names of the categories
- `name` (string): Friendly name of the smallest category
Each aforementioned sequence when referenced in an output template will be replaced by the actual value corresponding to the sequence name. Note that some of the sequences are not guaranteed to be present since they depend on the metadata obtained by a particular extractor. Such sequences will be replaced with placeholder value provided with `--output-na-placeholder` (`NA` by default).
For example for `-o %(title)s-%(id)s.%(ext)s` and an mp4 video with title `yt-dlp test video` and id `BaW_jenozKc`, this will result in a `yt-dlp test video-BaW_jenozKc.mp4` file created in the current directory.
