rules_oci supports two different registry implementation for the temporary storage within actions spawned by bazel.

1. By default we recommend using `zot` as it stores blobs on disk, however it doesn't support `Docker`-format images.
2. `crane` is memory hungry as it stores blobs in memory, leading to high memory usage.
However it supports both `OCI` and `Docker` formats which is quite useful for using `Docker` images pulled from the registries such as DockerHub.
2. `crane` is less tested alternative, however, it supports both `OCI` and `Docker` formats which is required to make images with `Docker` media types work.
