Add branch selection for Neuron and Spack (#237)

- Added parameters for SPACK_BRANCH, NEURON_BRANCH and CORENEURON_BRANCH
- Added logic to patch neuron spack recipe with the branch we want to test
- Install +debug variant of NEURON
- Export to the user the variable CORENEURON_BRANCH instead of sha1
- Also added this variable in the branches to build (needs testing)
