engine: remove czeror sequence parser

This file initially came from HLND, a Chinese GoldSrc recreation.
It turned out to be suspiciously close to the original version, down
to the comments and code style. We don't work with leaked sources here,
so remove it.

A proper parser should be reimplemented from ground-up, when we will
start working on CZDS support.
