ffmpeg: Re-write the module

[yshalsager]

Changes:

• There's no need to use ffmpegsave command anymore. All module commands will work with telegram files, local files, and direct links.
• ffmpegtrim has been replaced with atrim or vtrim command.

New commands

• x256 to encode videos using libx265, with the ability to use custom crf using -b flag.
• v2a to convert a video to audio, with the ability to use custom bitrate using -b flag.
• vscale to change video quality, with the ability to use custom crf using -b flag and encode with x256 using -c flag.
• vth to extract video thumbnail.
• vcompress to compress a video file to a given percentage.
• minfo to get media info using ffmpeg.

@yshalsager hey there , seems we need that save cmd since we can't have any visual feedbacks like in conventional android apps that first visualise the changes and exports them in single attempt , but here we need to do hit-and-trial in some scenarios like setting resolutions , etc so to optimise performance , the cmd may gradually affect it by saving last media locally. So , Can you please evaluate the scenario and present your views further , thanks

I have replaced ffmpegsave function with get_media_path_and_name that utilizes tg_download and url_download from download module (can be replaced with handle_download BTW), so it still visual progress exactly the same way as download module.
