Support for standalone build

[iperezx]

This is a pyvista more related issue, since its the python package that doesn't build on M1.

These are the steps we take:

* `git clone https://github.com/teamholtz/FastFuels-Python.git` if needed
* Comment out `pyvista==0.28.1` in [setup.py](https://github.com/teamholtz/FastFuels-Python/blob/master/setup.py)
* Rebuild wheel `python3 ./setup.py bdist_wheel`

Not sure if you want to support this, but the more archs the better right?

I don't think we use any viz from fastfuels directly (through pyvista) so maybe we can just use a standalone build. Maybe something like: pip install fastfuel[standalone]

I can help out with any dev or testing.

Sounds good, @iperezx. We're no longer using this repo internally, so feel free to jump in and remove the pyvista dependency and the Viewer class if need be.

@iperezx if you remove the pin to 0.28.1 for pyvista, does it build on M1?
