Tested on Arduino using Teensy 4.1

• ARM Cortex-M7 at 600 MHz
• Float point math unit, 64 & 32 bits
• 7936K Flash, 1024K RAM (512K tightly coupled), 4K EEPROM (emulated)
• QSPI memory expansion, locations for 2 extra RAM or Flash chips

Edit: I added a new updated file: examples/configs/user_settings_arduino.h that includes these macros for the AES_CTR example that would otherwise need to be added manually.

#define WOLFSSL_AES
#define WOLFSSL_AES_COUNTER

This user_settings_arduino.h file will be the new default user_settings.h for the next release of the Arduino-wolfSSL library. In the meantime, the changes can be made manually or with the install script.

I also included some minor changes to avoid warnings in Arduino related to hardening and not using client nor server examples.
