Pollutant Mod Support; OWA SWMM v.5.1.14

In this release, swmm-python adds support for updating pollutant mid-simulation! 🎉 . This feature should allow the users to use python and model almost any pollutant treatment. This feature has been a while in the making, and it is finally here. Kudos to @bemason and @karosc for their work in this release. Thanks to @jennwuu @michaeltryby for their continued effort in maintaining swmm-python

In v.0.9.0, we have included an updated version of OWA SWMM, v.5.1.14. We have also addressed build issues conda wheels, more robust testing, and several other refinements.

May your simulations always converge, and you never encounter dependency issues ☮️
