Laspy missing from environment.yml ?

[esgn]

Steps to reproduce :

1. Build docker image from source (docker build . -t myria3d)
2. Run an inference job using the created docker image. The following stack trace shows up and the inference fails. Looks like ign-pdal-tools does not install laspy directly.

Temporary solution

If I manually add laspy in the pip section of the environment.yml file and rebuild the docker image, then the inference is working fine.

- pip:
  - hydra-core==1.1.*
  - hydra-colorlog==1.1.*
  # --------- Documentation --------- #
  - myst_parser==0.17.*
  - sphinxnotes-mock==1.0.0b0 # still a beta
  - sphinx_paramlinks==0.5.*
  - ign-pdal-tools>=1.5.2
  - laspy

I probably should use laspy[lazrs] after having a look at ign-pdal-tools sources.
