feat(hardware): parallel mcu fw update capability

[pmoegenburg]

Overview

Currently, the run_update method is used to update the firmware for each robot microcontroller serially. This PR adds a run_updates method (and script) to update microcontroller firmwares in parallel.

Test Plan

• Ensure two separate microcontrollers' firmwares are successfully updated serially with one initial run_updates method call from the update_fws.py script. Total time 99sec for 2 microcontrollers.
• Ensure two separate microcontrollers' firmwares are successfully updated simultaneously with one next-iteration run_updates method call from the update_fws.py script. Total time 60sec for 2 microcontrollers.

Changelog

• Added simultaneous updating of robot subsystem microcontroller firmware

Risk assessment

Low. This builds off of the existing and proven serial updating process with proven software components.

This looks good to me now, but let's get the PR description a little more information before merging.
