v0.3.0

• Dynamic temperatures for rendering scale are now based on a moving average and have a minimum range applied.
• The thermometer precision can be truncated to reduce update frequency.
• Object recognition has been rewritten. Instead of a static threshold (the dynamic threshold was never implemented), a model of the background is built up and continuously updated. Non-background pixels are considered people once they've moved, and will continue be considered people until a configurable timeout is exceeded.
• Log output no longer contains ASCII escape sequences when logging to a file.
• MQTT connection handling improved, specifically when reconnecting.
• The MQTT base topic is now configurable.
• Melexis cameras can now be run at 0.5 FPS.
