* Updated the `decrypt` methods in `PlayReady` and `Widevine` classes to allow using `mp4decrypt`.
* Enhanced the `Config` class to manage decryption methods per service.
* Added `mp4decrypt` binary detection in the binaries module.
* Enhanced the `info` command to support both single `Path` objects and lists of `Path` objects.
* For lists, each path is now displayed on a separate line, improving readability.
* Maintained original logic for single `Path` objects to ensure consistent behavior.
* Introduced `MKVToolNix` and `mkvpropedit` binaries to the project.
* Updated the environment check to include required status for dependencies.
* Enhanced the `Tracks` class to raise an error if `MKVToolNix` is not found.
* Modified the `_apply_tags` function to utilize the `mkvpropedit` binary from the binaries module.
* Changed the binary retrieval for `Shaka-Packager` to use `find_binary` for improved accuracy.
* This ensures the correct binary is located and used in the environment checks.
* Refactored the `find_binary` function to utilize `binaries.find` for improved binary detection.
* Updated dependency path retrieval to ensure accurate results.
