v0.0.3

Adds initial Search support.

v0.0.2

Adds support for the autofocus Camera Module v3, plus configurable data expiry time in Redis and configurable image capture time.

v0.0.1

This is the most basic demo that uses SCAN to get all of the image keys from Redis, and which does not address the need to expire or otherwise delete images from Redis to stop it from filling up.

This version uses the Raspberry Pi Camera Module v2.1, but the only difference for using another camera that Raspberry Pi's PiCamera2 library supports should be the config.txt settings (see capture component README.md).

I'll aim to do another release that just updates this for the Raspberry Pi Camera Module 3 with autofocus, then maybe take this forwards to use the Search capability of Redis Stack.
