Martin Sloup f9ba8e9ccf Refactoring EPS32NVS library to Preferences library (#199)
* Refactoring EPS32NVS library to Preferences library

* Renaming all set* functions to put
* Added functions for float, double and bool

* Small redesign of Preferences API

* added type to put* function names
* for (u)int64_t used functions name with *(U)Long64
* added functions for long and unsigned long (same like int a unsigned int)
