OAuth Mandatory

[reustle]

I received the following email from Meetup. I'm assuming these changes will make this library break completely, until OAuth is integrated.

More info here: https://www.meetup.com/meetup_api/auth

We’re reaching out with two important updates which provide a better and more secure experience for all Meetup members. Here’s what you need to know:

Changes to our API access

• API Keys will be replaced by OAuth: We will be removing API keys on August 15, 2019 and requiring you to authenticate with OAuth.
• Move to OAuth soon for continued free API access: Until August 15, members will be able to apply for OAuth access free of charge. After August 15, anyone who wants to apply for API access through OAuth will need to have a Meetup Pro account in order to do so.
• We’re removing API version 2: Before August 15, you will need to switch to API version 3. API version 2 will no longer be available. You can find more information on our API updates and answers to common questions on our Help Center.

I have made some simple changes for the library to use OAuth tokens instead of the soon-to-be-phased-out API Keys. See this pull request. I used Requests-OAuthlib for the workflow to get OAuth tokens.
