ready for pip install locally

[tylerflex]

Need to settle on:

• repository name flexcompute/blah
• name for pip install pip install blah
• package nameimport blah as td

[momchil-flex]

I think the package name and pip name should be the same in the sense that e.g.

pip install tidy3d-beta
import tidy3d-beta as td

Having pip install tidy3d-beta but import tidy3d as td will be generally confusing, and even more so if old tidy3d is already installed.
