espnow: ESP8266: Add auto_connect & reconnects option to WLAN.config().

glenn20 · glenn20 · commit 325a7e21beef · 2022-09-29T15:26:22.000+10:00
Adds:
- WLAN.config(auto_connect=False) to stop the ESP8266 from
  automatically connecting to wifi networks after bootup.

- WLAN.config(reconnects=X) to limit the number of times to
  attempt to reconnect after becoming disconnected from a wifi
  access point.
