Updated error-check for out-of-range PWM frequency (an ESP32-S2 check) 

PWM has now been fully tested and verified with an ESP32 device under Arduino-ESP32 versions 1.0.6 and 2.0.0, and with an ESP32-S2 device under Arduino-ESP32 version 2.0.0.  Tests confirmed using both high (5000 Hz) and low (1 Hz or 5Hz) frequencies to ensure timers are correctly configured.

Next Task:  Update RFControl routines for 2.0.0 and ESP32-S2 compatibility.
