IR transmit example (#180)

* DWT-based microsecond delay * simple ir app (work only with NEC protocol and predefined address - command) * remove space from file name, add delay_us_init_DWT header * float-based delay us * init tim2 by CubeMX * fix simple pwm functions * simple pwm timer based ir nec protocol * ir gui test app Co-authored-by: aanper <mail@s3f.ru>
