What does this PR do?
In this PR #73, we stopped using Amplitudes includeReferrer setting in order to avoid a bug with anonymousIds. However, this broke the option to only set a referrer once per session, as our integration has no concept of amplitudes sessions. Referrers are being set with every page even when the option to only set referrer once per session is enabled.
This PR adds an option to revert to the old behaviour, where we let Amplitude handle setting referrer once per session. The default of the option will be a non-breaking change for existing users.
Are there breaking changes in this PR?
