I have been slowly working on a LAZ Python extension in https://github.com/hobu/laz-perf/tree/master/python
The basic compressor is working, but not LAZ. Some significant effort is still required, but the task is progressing a little. Sorry I can't provide more at the moment.

We support reading LAZ files (in a somewhat suboptimal way) if you have laszip on your path, but haven't implemented actual compression.

Got it. Right now I'm just shelling out to laszip, so it's not a huge deal. Do you have plans to integrate it in the future?

The preference would be to depend on Howard's completed tool to reduce the number of external dependencies needed. If it's something that you'd be interested in implementing, however, we could certainly implement a write mode for the Fake-mmap feature that adds laz reading capabilities in the meantime.

Thanks for all your help. I do have a workaround currently, so it's not the end of the world. I'll keep an eye on it though 👍
