Redirect URL should now be https

[trickytank]

Fitbit now requires the Redirect URL to be https, which might be causing an issue.

After running

token <- fitbitr::oauth_token()

I get the following error on the Fitbit website:

The app you're trying to connect did not provide valid information to Fitbit. Please report this issue to them.

Developer information: invalid_request - Invalid redirect_uri parameter value.

I am getting the same error, even when using an https URL - not sure how to fix this as it makes the library unusable :(
