How to install your own package from github

[thetazero]

Trying to install my package from here, via mip.install("github:Pycubed-Mini/MODL")

Has a package.json

{
  "urls": [
    ["MODL/__init__.py", "github:Pycubed-Mini/MODL/src/__init__.py"],
    ["MODL/frames.py", "github:Pycubed-Mini/MODL/src/frames.py"],
    ["MODL/IGRF.py", "github:Pycubed-Mini/MODL/src/IGRF.py"],
    ["MODL/mathutils.py", "github:Pycubed-Mini/MODL/src/mathutils.py"],
    ["MODL/orbital_mechanics.py", "github:Pycubed-Mini/MODL/src/orbital_mechanics.py"],
    ["MODL/sun_position.py", "github:Pycubed-Mini/MODL/src/sun_position.py"]
  ],
  "deps": [],
  "version": "0.0.1"
}

importing MODL gives an empty class, even though the files were correctly copied over to /home/thetazero/.micropython/lib/MODL/*.py
