maybe 45x slower since I've thrown out incorrect optimizations

For now I just have hardcoded lambda parameter. By adjusting it one
can obtain desired bitrate, by not touching it - desired quality.
I will try to make it follow ABR in the near future.

My task now is to create anchor for future practical implementation,
which will be faster but less optimal. Until then we have CPU cycles
waster ;)
