This PR tries to migrate the C function detect_stream_type()(src/lib_ccx/stream_functions.c) that handles the detection of video container to its pure Rust equivalent detect_stream_type(ctx: &mut CcxDemuxer) (src/rust/lib_ccxr/src/util/stream_detector.rs).
This migration follows Rust_migration_guide
