This modification add Blue dot indication in Livemap screen if error packet is decoded.
This mod will add also 4 buttons at the bottom left and right in Livemap screen: Scan, CH+, Pasue and Stop.
LZ4TU Scan algorithm must be applied before or after this patch for full "Nu Zayac, Nu Pogody" experience*!

'Scan' is used to return to "Normal Scan Mode", it is equivalent to double pressing Button1 of RDZ.
'CH+' will move the receiver to next QRG in QRG list, equivalent to short press of Button1.
'Pause' will freeze reception on current QRG for a time, defined in Screens1.txt @Field2 display settings, 
equivalent to short press of Button2. (More information in Screen1.txt )
'Stop' will stop Scanning algorithm permanently, it is equivalent to two sequential short presses of Button2.
It will be good to familiarize yourself with the UI of RDZ and LZ4TU Scan Algo Mod,
as these buttons can give unexpected behaviour if pressed in different sequences, but their main purpouse is:
1. To stop or pause scanning on desired channel.
2. Then move to next channnel or continue scan.
(Other suggestions are welcome, all modifications have comment LZ4TU at least!)

Applying the modification:
All user data will be reuploaded, so it is recomneded to read some files
from your current RDZttgo device and save them in ./Arduino/RX_FSK/data/
qrg.txt
networks.txt
config.txt
screens1.txt
You can use the integrated web editor at:
http://rdzsonde/edit.html?file=config.txt
or just copy raw content of each one file at
http://YourRDZ.domain.OR.IP/config.txt


Replace these two files in the directory ./Arduino/RX_FSK/data/
livemap.js ,  style.css
For information and changes in Scan algorithm read the comments in file Screen1.txt, inside this archive.
If you are using standard OLED display replace also "screens1.txt" with the one from this archive. *Note1

Upload files to FFS with Arduino or PlatformIO.
To upload SPIFFS with Arduino, go to "Tools>ESP32 Sketch Data Upload", ESP32FS plugin must be installed.
Note that ArduinoIDE 2.x versions are not supported by that plugin.

TNX to DL9RDZ for his VY GD job!
73, LZ4TU

*Note1: If other than standard OLED Display type is used, changes that have ben made in screens1.txt
have to be done also in the corresponding file screens1-5.txt and can be applied just with the internal editor at:
http://rdzsonde/edit.html?file=screens1.txt for example.

*Note2 "Nu Zayac, Nu Pogody" in analogy with the popular retro handheld game console "Nu, Pogodi!",
but now the game can be to catch the signals from falling sondes, instead catching of falling eggs. ;)
