Specifies configuration location

[RatCornu]

Hi! I'm the maintainer of the szurubooru package on nixpkgs, and I would like to extend it to oxibooru. To make things easier to package, it would be great to be able to specify at runtime the location of the .env file (though it can be bypass with DOCKER_DEPLOYEMENT set), and the location of the config.toml file.

This could be done by parsing the arguments of the command-line, for example with clap.

Hope it does not cause any trouble!

Yeah, no problem! I added an option to pass the command line arguments --env-path=<path> and --config-path=<path> to override the location of where the server looks for the env and config files. This is gated behind the load_env feature so I can remove the dotenvy dependency from the Docker build, but this feature is enabled by default to make local development easier.

I've also removed the DOCKER_DEPLOYMENT flag, as the env/config loading is now controlled by the feature.

Thanks! I'll look into it when I will have time

It occurred to me that the path to FFmpeg was hard-coded assuming a Docker build, so I also added the ability to specify that path with --ffmpeg-path=<path>.
