Flag for clean cyclic logging files

[jiargei]

Subject of the issue

You already implemented a cyclic logging, also for long time observations (see #86 , and #43 ) which works actually fine. It would be nice to have a flag (logging to set the observation periods to propper time periods. Lets name the variable "useCleanLogTimePeriod (0 or 1)"

Example Szenario

I want to use my RTK Explorer to log several days and generate hourly files (3600 s or 60 m). I start measuring at 07:49:41.. so the first file will be named

By setting "useCleanLogTimePeriod=0", the already implemented behaviour will generate files:

• "SFE_Facet_yymmdd_074941.ubx"
• "SFE_Facet_yymmdd_hh4941.ubx"

By setting "useCleanLogTimePeriod=1", the next files would be:

• "SFE_Facet_yymmdd_074941.ubx"
• "SFE_Facet_yymmdd_080000.ubx"
• "SFE_Facet_yymmdd_hh0000.ubx"

So to check if a new file should be created, add something like "current gps time modulo maxLogLength_minutes == 0". I could'nt find the implementation in the code.

Especially for long time observations it would be nice to have "clear" filenames and see a feature like this in some of the next releases!

This is not an issue, it is an enhancement! Great work by the way! The firmware is really nice to handle!
