Integrate Channel Impulse Response Database (CIRDB) to enable playback of precomputed realistic channel taps in vrtsim, with runtime selection via YAML metadata. Features: - Read precomputed channel taps from binary database with YAML sidecar - Runtime enable via --vrtsim.cirdb with optional paths (cirdb_yaml, cirdb_file, cirdb_path) - Channel parameter configuration: model_id (TDL-A..E), delay spread (ds_ns), UE speed (speed_mps) - Fallback to existing channel model options when disabled - Time-driven snapshot progression based on elapsed simulation time Fixes: - RNG initialization: Add randominit() call before gaussZiggurat() - FlatBuffers linking: Handle both 'FlatBuffers' and 'flatbuffers' package names when working with external channel emmulator - Address review comments: use pthread directly, update calloc_or_fail, simplify CMake
