[DHTlib] Correct library.properties architectures value
The previous architectures value of atmelavr causes the example sketches to appear under File > Examples > INCOMPATIBLE > DHTlib and also a warning to be displayed during compilation of any sketch that includes the library:

WARNING: library DHTlib claims to run on (atmelavr) architecture(s) and may be incompatible with your current board which runs on (avr) architecture(s).

fad0391f62 Add timing analysis, format output, limit execution cycles
To increase the usefulness of the example, I added the measurement of
the complete cycle, which is the important figure. The reading time
itself, though interesting, is not the limiting factor according to the
datasheet.
Additionally, I updated the printing instructions to create a nicely
formatted output and limited the number cycles necessary to reach "del
== 0".

174a065598 Replace delay with delayMicroseconds to let it work while interruppts are disabeled.
In multihreaded environment (I used NilRTOS) its usefull to disable interruppts while reading the sensors. However delay() requires interrupts to be enabled. If you read more than one sensor in a sequence the 2nd one gets spurious DHTLIB_ERROR_CONNECT errors. Timing issues with the wakeup delay().
They don't used to happen it interrupts are enabled. Replacing delay() with delayMicroseconds() solved this issue.
