Add copcesium to software implementations

[Jangmyun]

Hi maintainers,

I've been building copcesium, a CesiumJS data source for streaming COPC point clouds — it fetches only the octree nodes visible to the camera instead of downloading the whole file, and flies to/colors/filters the dataset out of the box.

Live demo: https://copcesium.vercel.app/ (streams datasets up to ~52 GB / 9.7B points)

It's still evolving, but it's published on npm and MIT-licensed, so I wanted to add it here in case it's useful to others working with COPC + Cesium. Happy to adjust the entry's wording, or hold off if it's premature — let me know what you think.

Thanks for flagging this — you're right that we should have been crediting the data we've been relying on.

We've added examples/DATA_SOURCES.md, which credits the origin of each sample dataset used across our four examples, verified by reading each file's LAS/COPC header directly and cross-checking against primary sources where possible. It also notes that most of these files are hosted in the hobu-lidar bucket by Hobu, Inc.

The example UIs now link to this file directly — right below the dataset picker in the simpler examples, and alongside a per-dataset credit line in the Info panel of the fuller ones.

Really appreciate Hobu making all of this data so easily streamable — it's what made these examples possible in the first place. Let us know if anything looks off or if there's an attribution you'd rather see stated differently.
