v1.22.0

Summary

This release includes two new features:

• dqlite clients now search for the current leader by connecting to several nodes of the cluster in parallel (#292, thanks @cnnrznn). The level of parallelism can be configured with the new WithConcurrentLeaderConns option (#303, thanks @masnax).
• The new WithRolesAdjustmentHook option allows applications that use go-dqlite to react to changes in cluster membership and roles (#301, thanks @masnax).

It also includes several bug fixes and performance improvements:

• Introduce a timeout for connecting to the leader in the dqlite-demo example program (#295, thanks @letFunny).
• Fix a panic caused by reading from a closed channel when accepting new client connections (#304, thanks @marco6).
• Copy blob values from server messages in bulk instead of one byte at a time (#297, thanks @marco6).
• Fix a panic causes by an unset field in the client's Rows object (#308, thanks @marco6).
