add error checking and diagnostics

[YaraShahin]

Changes:

• Added error checking in read() to deactivate if any alarms
• Added diagnostics of which alarm got invoked in clear_alarms function
• Added how to run the sim or robot from the pc to readme
• Moved cleaning alarms and initial read & write of states to activate. Why? because the error clearing function was getting called before the non-blocking connect() finished. See log:
