* 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)
