Co-authored-by: Thaha Mohammed <[email protected]>

These commits update the v8 add ClusterClient support (#41)

Update to Redis 8.11 and add GetEx Support (#40)

Make the library thread safe (#39)

This commit makes the library thread safe by adding a local `sync.Mutex`
in the mock client and implementing all the`mock.Mock` methods that use
the internal (and not published) `sync.Mutex`

Before this commit, all the tests run with the `-race` flag using this
library would fail
