Had to adjust T1 and T2 to t1 and t2 since the otheres are used by the ESP32 library.

Results:

• Arduino Leonardo: 8.00 MIPS
• Arduino Uno: 8.01 MIPS - should be only 1.21 MIPS …
• Mega 2560: 7.92 MIPS
• ESP8266: does not run
• ESP32: 14.94 MIPS

Whetstone 1.2

• Arduino Leonardo: 7.96 MIPS
• Arduino Uno: 8.01 MIPS
• Arduino Mega 2560: 7.92 MIPS
• Wemos Lolin ESP32: 70.62 MIPS

Calibrates itself, more output data. See this documentation. I got up to 680 MFLOPS and 2292 MWIPS.
