Allow loading a policy bundle from a specified path

[carabasdaniel]

According to the configuration of the runtime topaz should be able to load a bundle from a configured path on the disc.

Currently there is no method to configure this behavior using the topaz CLI.

Allowing topaz to run with a bundle loaded from a folder would improve the experience of writing your policy as editing your rego definitions would be reflected directly into the loaded runtime bundle, allowing you to to interact with your loaded bundle a lot easier.

Topaz has the ability to run policies from the local policy OCI store. This feature would enable a smoother rego authoring experience when editing policies by immediately reflecting changes to the policy source files.
