pure D mpeg2 decoder

[Ruslan Mullakhmetov via Digitalmars-d-announce]

Hi all!

I saw pure jpeg decoder was announced recently and I decided to 
publish pure D mpeg2 decoder that I wrote just for myself, with 
study aims.

I didn't test it exhaustively, so don't judge me for bugs)

Currently it supports only progressive sequences with no B frames.

As for performance, it's 5 times slower than ffmpeg 
implementation, optimizations are required.

Does someone want to write pure D AVC or HEVC decoder/encoder?  =)

P.S. It sometimes has some artifacts, I didn't try to fix them.
