Feature: Project Config File

If I understand it correctly, presenterm's order of precedence for configs is

1. --config-file
2. PRESENTEM_CONFIG_FILE
3. $HOME/.config/presenterm/config.yaml

I am not sure, why user-level / system-level configs for presentations are a thing but there probably are reasons. To me, it's much more presentation specific and I solve this with direnv and the environment variable to load a config file from the project folder. My suggestion is to add a presenterm.config file to the list above to support this natively.
