Replacing PyMC3 plots w/ Arviz plots & sigma Param change [Part 5] (#23)

* 🎨 Update plots from pymc to arviz dependencies & replace param sd with sigma

* ⏪ Revert metadata changes in notebooks

* 🐛 Set core=1 on pm.sample and update submodule reference

* 🎨 Add version for Pymc3 and remove warnings import
