Convention for multiple configuration files

[nathan-muir]

Problem

Users can accumulate many different credsmash configurations.

It's tedious to reference them by their full path, ie,

credsmash --config ~/.config/credsmash/xyz.cfg find-one 'db*'

Proposed Solutions

Option 1: Allow for multiple "sections" in a single file
Option 2: Provide a shorthand for a particular filename pattern, ie, -n xyz to load ~/.config/credsmash/xyz.cfg
