Installation failure due to weak specification of trimesh version

[jsuarez5341]

Loosely specified "trimesh[easy] >= 3.15.5" fails with default pip solver. Had to install trimesh[easy]==3.15.5. Please consider pinning the version. Error is:

ERROR: Could not find a version that satisfies the requirement embreex; extra == "easy" (from trimesh[easy]>=3.15.5->avalon-rl) (from versions: none)
ERROR: No matching distribution found for embreex; extra == "easy" (from trimesh[easy]>=3.15.5->avalon-rl)

This is inside a fresh docker with base nvcr.io/nvidia/cuda:11.7.1-runtime-ubuntu20.04
