ESP32: Interrupts do not get re-enabled

[hajosc]

It appears that at least gcc 14.2.1 does not call the class's ~InterruptLock() destructor and hence interrupts don't get re-enabled. I rely on interrupts for other functionality and they stop forever once a DHT read is triggered.

Either keeping interrupts on (my ISR is very short) or disabling (1x) & re-enabling (3x !!) interrupts in the read() function both work as expected.

This might also be the casue of #211.
