[Feature request] Reduce bin size by excluding serial log from code

[tonhuisman]

Similar to sparkfun/SparkFun_SCD4x_Arduino_Library#3 I'm still working on reducing code size for ESPEasy 😃

So in that same line, I'm proposing to add a similar compiler flag for reducing the bin size.

//Enable/disable including debug log (to allow saving some space)
#ifndef MAX1704X_ENABLE_DEBUGLOG
  #if defined(LIBRARIES_NO_LOG) && LIBRARIES_NO_LOG
    #define MAX1704X_ENABLE_DEBUGLOG 0 // OFF/disabled/excluded on demand
  #else
    #define MAX1704X_ENABLE_DEBUGLOG 1 // ON/enabled/included by default
  #endif
#endif

I'll open a PR to get that included.

It took a little (more) time, but the PlatformIO registry now has picked up the latest release 🍾
