api: GET /files includes dirs, GET metadata (#18)

* api: GET /files includes dirs, GET metadata

Modify GET single file endpoint to use :file_path instead
of :file_name
Modify /print/start to use :file_path instead of :file_name
Modify GET /files response to also return directory vec,
allowing the UI to hit one endpoint for filescreen population
and eventual sorting/filtering
Add GET /files/:location/:file_path/metadata endpoint for getting
metadata for a single file

* api: Suppress warnings on build, let clippy handle it

* api: fix sl1 processing to account for relative paths

* api: revert config crate version

Revert config version to 0.13.4 until the case bug is resolved
rust-cli/config-rs#531

* api: move file_path to query params for /file and /file/metadata

Move /files/:location/:file_path to /file with query params
to support file_path parameter with slashes
Move metadata endpoint to /file/metadata, with same query params
Rename location category param to location

* api: migrate start endpoint to query params
