Feat/sof strategy

[Robert-W]

• Integrates SOF Strategy from @asymmetrik/sof-strategy.
• Removes old code
• Updated relevant documentation

This does contain a potentially breaking change, which is that the authentication no longer requires a url to a strategy, which was a little confusing when strategy was in node modules. It now accepts the strategy as a module. To enable authentication, they must provide the same environment variables in the same manner, it is only breaking in the sense they need to rerun npm install when upgrading since their is a new dependency or if they added their own strategy.
