Requires llvmlite

[deeuu]

Hey,

In a fresh conda environment, pip install -r requirements.txt failed.

It seems I need to install llvmlite first, e.g.
conda install -c numba llvmlite

numba and llvmlite should come as a dependency of librosa. Unfortunately they missed shipping the llvmlite wheels in time which is why pip fails

See here: numba/numba#2918

This reminds that I will remove the requirements.txt as I like to move over to pipenv's Pipfiles. We an add a conda environment.yml as well if you like
