Adding CoInfra dataset

[NingMingHao]

Thanks for organizing this excellent repo for cooperative perception and dataset!

Could you please consider to add our recent work into this repo, where we proposed CoInfra, a real-world, large-scale cooperative perception system and dataset designed to support research in multi-agent perception, especially under adverse weather conditions (snow, rain, freezing rain). It features 14 synchronized infrastructure nodes, each with a LiDAR and dual cameras, deployed across a shared region for full-scene coverage.

We also provided the hardware list and software stack to build customized cooperative sensor node system.
