How to add a new Service

serviceName below is the name of the Service you're adding

currently, pocket is already included

Oauth Page

in the src/pages/oauth folder, add a new file serviceName.html
- this page can be a copy of the pocket.html page in that same folder
- one thing to change: service="serviceName" on the root div
in src/manifest.json, under web_accessible_resources, add this new ./pages/oauth/serviceName.html page

in src/services create a new serviceName folder
- the index.ts of this folder should export:
  - an object named serviceName that adhere to the Service interface
    
    this obviously means that you have to implement those methods
  - a string literal type whose value is serviceName
in src/services/index.ts
- import both items from the new serviceName mentionned above
- add the type to the existing ServiceNames type (with a |)
- add the object as a key of the existing exported services object
