Memory leak when reinstatiating sensor object

[ScruffR]

As I found out here, there is a potential memory leak when using multiple instances of that library https://community.particle.io/t/ds18b20-switching-pins-during-execution/25727/15

This is easily fixed with the intrdocution of a destructor

DS18B20::~DS18B20() {
    delete(ds);
}

And if you're at it, could you also replace these macros, please?

• digitalWriteFastHigh()
• digitalWriteFastLow()
• digitalReadFast()

with the now available functions

• pinSetFast(_pin)
• pinResetFast(_pin)
• pinReadFast(_pin)

One the other hand it might even be better to remove the "private" implementatino of OneWire and just add a note to import that dependency (this will make getting this lib ready for Libraries 2.0 easier too).

Will do and thanks for the input. I need to get into the Lib 2.0 implementation, I spent 2 hours creating gulp tasks to check for updates, extract lib core files and moving them to the appropriate folder for testing. I hope the new lib system can be used more like a package manager like npm, bower, etc.
