Support for non void fix init(), feed prepopulated fix to module #107

Hi, First of all thank you for the wonderful library, really amazing work ! I had a request regarding the apparent impossibility to feed a pre-populated fix to the GPS (NEO-M8N in our case) in order to reduce Time To First Fix greatly after a module restart. This is of interest in the case of an autonomous system going to hibernation in order to limit power consumption.

Upon reboot of the module, I would like to feed it the previously recorded fix and/or an up to date time from a low power RTC I have on the side.

I could not figure out how to that with NeoGPS at the moment.

Thank you in advance for your support ! Quentin

Hi, I am also using NEO-M8 ... Does your hardware supply power to the V_BCKP pin in hibernate mode - this helps greatly.
