### Releases v1.0.6

1. Initial coding to use (ESP)AsyncWebServer instead of (ESP8266)WebServer. 
2. Bump up to v1.0.6 to sync with [BlynkESP32_BT_WF library v1.0.6](https://github.com/khoih-prog/BlynkESP32_BT_WF).

Important Notes:
1) Sketch is ~0.9MB of code because only 1 instance of Blynk if #define BLYNK_USE_BT_ONLY => true
2) Sketch is very large (~1.3MB code) because 2 instances of Blynk if #define BLYNK_USE_BT_ONLY => false
3) To conmpile, use Partition Scheem with large APP size, such as
3) To conmpile, use Partition Scheme with large APP size, such as

c) No OTA (2MB APP, 2MB FATFS) if use EEPROM
