v0.1.15

This release of Mayu focuses on optimisation.

Additionally, Mayu's images available on Docker Hub now include linux/arm64 builds, where before only linux/amd64 builds were available.

Change Notes

• Pre-cache all theme images in memory to avoid having to read from disk multiple times per request
• Optimise database queries by merging three queries per request into one query per request
• Add additional runtime error logging to the database and cache modules
