Videohash

- Fix typos in some Exceptions.
- added a param frame_interval in VideoHash class for specifying frame rate. (-r param of FFmpeg.)

- Removed youtube-dl from the dependency now the package now solely uses yt-dlp for downloading videos.
- VideoHash now works on python 3.10 post the 3.10 wheels of SciPy.

- Improved docstrings, useful for IDE/editor autocomplete.
- FASTER: Use f-strings for String interpolation instead of c-style.
- FASTER: Extend the rows of the wavelet hash to the instance bit list, no need to waste resources by generating the bit list from the bitstring.
- Use yt-dlp as the default downloader, yt-dlp avoids throttling issues with YouTube.

Update the pageon PyPi

- More type annotation
- Avoid changing types of variables in runtime.
- Avoid changing values of parameters of methods(they stay the same throughout their life).

- The videohash code is now type annotated.
- The black bars in videos are removed before calculating the videohash value.
- The extension of the downloaded video is set to .mkv if the video lacks an extension because the Matroska container can contain all codecs.
