Pip install complexities

[sapols]

It's not currently possible to install every PyHC package in a single pip call since a few of them require special treatment. Here's what we're doing at the time of this writing:

# Install PyHC packages with pip (SpacePy, Kamodo, and pySPEDAS separately)
RUN pip install --no-cache-dir numpy==1.24.3 && \
    pip install --no-cache-dir spacepy --no-build-isolation && \
    pip install --use-pep517 --retries 5 --no-cache-dir -r /app/requirements.txt && \
    pip install --no-cache-dir git+https://github.com/nasa/Kamodo.git && \
    pip install --no-cache-dir pytplot-mpl-temp && \
    pip install --no-cache-dir pyspedas

Causes:

1. SpacePy fails to install if numpy isn't already installed and you don't use the --no-build-isolation flag
2. Kamodo is being installed from GitHub not PyPI
3. pySPEDAS fails to install if pytplot-mpl-temp isn't installed first

1. Might no longer be an issue after the SpacePy 0.5.0 release.

1. is indeed no longer an issue after SpacePy 0.5.0.

3. pySPEDAS installs fine on its own now and will pull in the correct pytplot-mpl-temp

So the only package getting special treatment now is Kamodo which gets installed from GitHub:

# Install PyHC packages with pip (Kamodo separately)
RUN pip install --use-pep517 --retries 5 --no-cache-dir -r /app/requirements.txt && \
    pip install --no-cache-dir git+https://github.com/nasa/Kamodo.git
