🪲[Bug] Sync freezes indefinitely

[kcw-grunt]

Problem

When the user tries to perform a full sync the connected node could freeze and stop sending blocks

Background

The users all are dependent on the quality of the Litecoin network near them.
Here are the steps to perform sync:

1. Client (Android or iOS) asks loafwallet-core to start syncing.
2. Asks to gather available peers (nodes) ip addresses
3. Randomly open a session with the peer (node)
4. Client asks the peer for a certain Litecoin block
5. Client checks the block for any matching addresses and saves any into the database while add the values
6. Client asks the peer for a the next Litecoin block

So client is waiting on the peer and there is no current way to reset or disconnect from the peer

This may be the location where a disconnect can occur if the peer stuck on the same block
