v2.7.7 - Remove IFA/IDFA

Removing using IFA as distinct id
#389

Beginning with this version, Mixpanel no longer uses the IFA(ID for Advertisers) but uses a randomly generated UUID as the default distinct ID instead. After you call reset, Mixpanel generates a new distinct_id by default. This ensures that multiple users on the same device are not assigned the same alias.

If you want to use IFV(identifierForVendor) as the distinct_id, you can set
MIXPANEL_UNIQUE_DISTINCT_ID in build settings Active Compilation Conditions on the Mixpanel framework target. After you call reset, the IFV will not change. However, when a user removes and then re-installs the app, the IFV will change with each installation.
