This was raised by Houston Smith from UW-Madison, trying to install PySpecTools through the Anaconda Navigator on Windows, returning this error:

ResolvePackageNotFound: 
- ncurses=6.2
- libstdcxx-ng=9.1.0
- libgcc-ng=9.1.0
- libedit=3.1.20191231
- libgfortran-ng=7.3.0
- readline=8.0
- ptyprocess=0.6.0
- libffi=3.3
- ld_impl_linux-64=2.33.1

I believe these are Linux only packages, and for whatever reason --no-build when creating conda.yml left them in. Will remove these in conda.yml and see if it solves this issue.

Modifying conda.yml to remove linux packages

This hopefully addresses issue [#15], where a Windows installation
tries to look for Linux-only libraries.

Improving Windows setup by removing Cython
8afd5b9 
Previously I had implemented some "fast" routines using Cython which
were poorly written loops that were marginally faster than looping using
NumPy arrays. These have now been superceded by comparably faster
routines using JIT compilation in Numba, which now reside in the
`lineshapes` module.

For this reason, I am removing Cython routines from the library, which
in turn means we no longer need to run cythonize during setup time,
which had always plagued Windows installations. This references issue
[#15].

Seems like removing Cython routines largely helped with getting the installation to work on Windows. Ideally I'd like to have CI setup to build in Windows environments, but apparently this is not yet so straightforward.
