Add simulation module to Nemo

Add a simulation module, that emulates field-oriented control on a brushless motor. This can be used to tune the controller's gains, and evaluate the system's response to torque, velocity or position commands.

v1.0.2: Code quality

This release includes only minor fixups:

• remove calls to soon to be deprecated functions
• reformat source code using black
• update README format to display nicely on pypi
• make CI more stable by using fixed versions of dependencies

Add windows binary & logo

• Add a Windows binary of the application.
• Create project logo.
• Improvements to the motor helper dialog: better initial option guess ; the values are now derived so as to leave the input motor unchanged by repeatedly opening / closing the dialog.
