Allow video_open to accept a buffer as the input as well properly check the supplied file type

Is your feature request related to a problem?

playing videos in GM is cool, I also understand YoYo doesn't want to ship a codec with GM Currently, the function does some black box stuff as well, and will only accept file names/paths that end with a .mp4 extension you can supply the exact same file but with a different file extension and GM will not play it like a video file, despite being a mp4 file just renamed.

Describe the solution you'd like

so not only should the file extension name thing be changed, it would be nifty if we could supply a buffer to the function and have the video played from that buffer, under the hood GM already loads the video into a buffer, so it would be simple to just supply our own for it to use.

Describe alternatives you've considered

I have tried doing this myself but the function will not accept anything other than a file or file path with a specified.mp4 extension so the function should be tweaked to be smarter about the file being supplied even if the .mp4 is named filename.myt for example
