FIXED "heap != NULL && "free() target pointer is outside heap areas" on BLERemoteCharacteristic::readValue()

[elettro1]

When calling the function BLERemoteCharacteristic::readValue() sometimes it gave this error:

[D][FreeRTOS.cpp:158] take(): Semaphore taking: name: ReadCharEvt (0x3fff8f00), owner: <N/A> for readValue

I saw now that the problem has been fixed in the reposity

https://github.com/nkolban/esp32-snippets/blob/91e1571dd5bd433e107f92e1588780ee22fed42e/cpp_utils/BLERemoteCharacteristic.h#L77
The solution is the same, to be included in the header or in the constructor
m_rawData = nullptr;

But if you don't update the fixes, those who use platformio still have these issues.

We no longer track nkolban's esp32-snippets repo. Reason is that there is nobody there that is willing to push the updates to the Arduino lib. Merging here :)
