Update Example to include TwitterV2, fix TwitterV2 crash

[IRelaxxx]

Add TwitterV2 Provider to the example, the Twitter provider does not work if you only have the Essentail API Access Level because it uses the v1.1 API to get userInfo(see Twitter API Docs)

Changes to TwitterV2 Provider per Twitter API Docs

• Add Response fields, only id,name,username are default. Added description,profile_image_url,location
• Remove E-Mail check/cast because the v2 API user info API does not contain the E-Mail
• Add check for location because it can be nil if the user did not set a location
