Add install instructions for HSL on windows

[avdudchenko]

This adds simple instructions on how to add HSL binaries to windows conda install of cyipopt. - tested only on my machine, so hopefully it works for others.

One comment for adjustment, but otherwise thanks for the helpful addition!

The test failures are because scipy 1.13 broke things. If you change to scipy>1.8.0,<1.13 to .github/workflows/tests.yml:

https://github.com/mechmotum/cyipopt/blob/master/.github/workflows/tests.yml#L58

the tests should pass.

I tried that, but not sure where I am configuring it wrong (says file not found). ( I never really worked with github workflows or mamba.) also trying scipy>1.8.0,<1.13.0. but doubt that is the issue.

Run mamba install -q -y -c conda-forge "ipopt=3.14" "numpy>=1.21.5" "pkg-config>=0.29.2" "setuptools>=44.1.1" "scipy>1.8.0,<1.13" "pytest>=6.2.5" "cython=0.29.*" mamba install -q -y -c conda-forge "ipopt=3.14" "numpy>=1.21.5" "pkg-config>=0.29.2" "setuptools>=44.1.1" "scipy>1.8.0,<1.13" "pytest>=6.2.5" "cython=0.29.*" mamba list pytest shell: C:\Program Files\Git\bin\bash.EXE -l {0} env: INPUT_RUN_POST: true CONDA: C:\Miniconda3 CONDA_PKGS_DIR: C:\Users\runneradmin\conda_pkgs_dir IPOPTWINDIR: USECONDAFORGEIPOPT bash: line 1: 1.13: No such file or directory Error: Process completed with exit code 1.

You don't have to debug that. I'll work on it.
