[pdal] PlyReader inspect QuickInfo

[Daniel Brookes]

Hello point cloud people!

One part of the PDAL C++ API we utilise in our application is the QuickInfo inspection to relatively quickly determine info about a point cloud file. We use this for some UI components. This works great for LAS and E57 but we recently had a request for this to work for PLY files as well.

I'm happy to submit a PR to extend PlyReader for this but a problem I realised is that the PLY header does not specify bounds (or SRS) which would leave the QuickInfo incomplete (without reading the entire file to determine bounds, which defeats the purpose).

What's the feeling around that? Is it reasonable for the QuickInfo bounds to be empty and we fill out the parts we can - which for PLY would be the point count and dimensions.

Regards,
