Add new plugin danmu

[HankunYu]

Description

Add a new plugin danmu. This plugin use dandan api to generate .ass subtitle files to play danmu with local video files.

This extension allows users to select a video file (.mp4 or .mkv) in Finder. It calculates the MD5 hash of the first 16 MB of the video file and searches for the corresponding danmu file using the Dandan API. The plugin then generates two types of danmu files: one containing only the danmu comments and another that includes the original subtitles along with the danmu.
