* Bump AWS SDK to v1.33.3 * Bump redis version
The Redis library was pinned to an older vesion using gopkg.in. This updates to latest version and pins w/ go mod. https://github.com/harlow/kinesis-consumer/issues/93
As we work towards introducing consumer groups to the repository we need a more generic name for the persistence layer for storing checkpoints and leases for given shards. * Rename `checkpoint` to `store`
