Fixes 38 which, due to changes on Tandem's side, prevented tconnectsync from connecting to Tandem's servers.

**Prior releases are likely to be broken by Tandem's changes, so please upgrade.**

**Breaking change:** The IOB synchronization feature was disabled by default, because it is not being utilized in the Nightscout UI at this time and is only available through the Nightscout API. It can be re-enabled with the `--features` flag.
