Set up initial config architecture

[lukeocodes]

Having spoken with Adam, we plan to use a well known pattern for config storage.

This follows how AWS's SDK operates. stores a raw API key (in our case, purposely created for CLI operations), in %HOME%/.config/%APPNAME%/%FILENAME%

$ cat ~/.config/deepgram/config.yaml 
api_key:
    accesstoken: 361fa0a8376414ba897a67609476e966d54d1cf1
    projectid: ""
