v1.5.0 to enable scan of WiFi networks

### Major Releases v1.5.0

1. Enable scan of WiFi networks for selection in Configuration Portal. Check [PR for v1.3.0 - Enable scan of WiFi networks #10](khoih-prog/WiFiManager_NINA_Lite#10). Now you can select optional **SCAN_WIFI_NETWORKS**, **MANUAL_SSID_INPUT_ALLOWED** to be able to manually input SSID, not only from a scanned SSID lists and **MAX_SSID_IN_LIST** (from 2-15)
2. Fix invalid "blank" Config Data treated as Valid.
3. Permit optionally inputting one set of WiFi SSID/PWD by using `REQUIRE_ONE_SET_SSID_PW == true`
4. Enforce WiFi PWD minimum length of 8 chars
5. Minor enhancement to not display garbage when data is invalid

Static STA IP and DHCP Hostname as well as Config Portal AP channel, IP, SSID, Password can be configured. Config. Data saved in ESP8266/ESP32 LittleFS, SPIFFS or EEPROM. Multi, Double DetectDetector or Virtual CP Switch feature permits entering CP as requested. Configurable Customs HTML Headers, including Customs Style, Customs Head Elements, CORS Header.",
