Shaman was made on Linux, using the `path` module, which only supports
forward slashes. This mostly replaces `path` with `path/filepath` to use
native paths and increase Windows compatibility.
The work isn't done yet, though.
Flamenco v2 allowed separate configuration of the Shaman file store and
checkout paths. This is now just one setting for "the storage". The file
store will be in `{storage}/file-store` and the checkout will happen in
`{storage}/jobs`.
This is not yet working, it's just a direct copy of the Manager of Flamenco
2, with Logrus replaced by Zerolog. The API has been documented in
flamenco-manager.yaml as a starting point for the integration.
