Jira Link: https://toruslabs.atlassian.net/browse/PD-3692?atlOrigin=eyJpIjoiZjU3ZWRjYjU1MWJjNGE1NDllNGU4MGJiMWVjNzc3NmMiLCJwIjoiaiJ9

Description

• The AdaptiveBroadcastChannel class is designed to add fallback during channel post message and synchronization issues between senders and receivers in a broadcast communication scenario. It achieves this by:
• Creating a separate channel for each communication method, allowing all methods to listen simultaneously.
• Implementing adaptive listening, where all instances listen on all channels but primarily use the current active method for sending.
• Enabling seamless method switching, allowing receivers to automatically adapt to the sender's method changes without manual intervention.
• This AdaptiveBroadcastChannel can be opt in by the user of the package
