Feature: Save settings in local storage

[bdougie]

Type of feature

🍕 Feature

Current behavior

I use the same settings every-time I generate a description. But every-time there is an update or the cookie refreshes I need to save the settings again. It would be nice if we save the user settings in local storage.

Suggested solution

localstorage is preferred, but we could potentially store a settings JSON.

"settings" : {
  "Description Source" : "Commit Message",
  "Description Type" : "Formal"
}
