feat: Add --no-cache option. (#5)

bvanelli · web-flow · commit f7ad6e403513 · 2026-03-16T16:36:35.000+01:00
Forces all layers to be pulled regardless of them being already cached in the file system.

Also prevents the layer from being saved into cache when pulling the image (for CI jobs, for example).
