Add installation instructions for Anaconda users

[Iztok Fister Jr.]

Hi @spelap,

please extend README with installation instructions for Anaconda users (especially for Windows ecosystems).

If there is a chance, please try to provide also conda-build recipe for this package. https://docs.conda.io/projects/conda-build/en/latest/concepts/recipe.html

A very similar recipe was created for NiaPy package: https://github.com/NiaOrg/NiaPy/tree/master/conda
