✨FEATURE: Add Failsafe

[Witty-Wizard]

Overview

Implement a failsafe mechanism that triggers after a specified time without receiving a signal. The system should set predefined failsafe values to the outputs when no signal is detected for the specified duration.

This would enhance safety and reliability for projects using SerialIO.

Tasks

• Using timing mechanism to check the time the last packed was received, and if no new packet is received for a long time then enable failsafe flag and output failsafe values in the channels.
