This is useful for ESP devices that have serial GPS devices connected to non-standard pins (i.e TTGO T-Beam). It is possible to initialize and use these devices without separate calls to Serial.begin().
I'll probably update the lib to just take a pointer to the hardware serial, which will push serial configuration and the "begin" method outside of this library. Issue #14 created to track this.
