PIDKiln v1.3 - mostly bugfix release

• fixed more issues created with FS/SPIFFS changes in ESP32 2.0.x framework (graph where missing data, logs and csv where not filled with data)
• fixed grave bug in program subroutine (it had too low priority to work reliable - causing slow updates, and not reliable execution of the program itself)
• fixed MAC address display (was shown in reversed order), add some new chip information to debug screen
• fixed some more possible memory errors in freeing memory
• cleaned/fixed html language and encoding definitions
• add web server simple error handling

PIDKiln v1.2

1.2 (2021.12.02)

• Updated SPIFFS handling to make it compatible with ESP32 2.0.x+ Arduino framework (it has change silently)
• extended error reporting for MAX31855 and thermocouples
  [ADDONS] Temperature sensor A readout: Internal temp = 26.1 Last temp = 24.2 Average kiln temp = 20.9
  [ADDONS] ThermocoupleA not connected
  [ADDONS] MAX31855 for ThermocoupleC did not respond
• lowered SPI clock value for less errors during communication handling (in MAX31855 library)
• new feature allowing grace count for errors of MAX31855 readout. Errors increases counter until reaching MAX31855_Error_Grace_Count = 5, proper readouts decrease counter (not reset).
• you can now use Wroom modules (without PSRAM) - change MALLOC definition in PIDKiln.ino
• fixed stupid stack overflow in IP display routine that could cause stack smashing

PIDKiln v1.1

1.1 (2020.03.15)

• added MAC address information in LCD Info screen (if you would need to add it to your WiFi filtering)
• get rid of awesome font - it required Internet and it's much too heavy for two icons - replaced with PNGs
• replaced index_local.html (with locally provided large JavaScript files for WiFi without Internet) with preference switch - whether to send file locally or remotely (recommended)
• fixed MAX31855 library to detect disconnection
• introduced Syslog feature - to transfer remotely (by UDP) all debug information. You can choose whether you want to have them on serial, syslog or both.
• add 10nF capacitor to thermocouple input pins - it's a must to have reliable readout (I've learned it hard way)
• switched from Adafruit-MAX31855 to enjoyneering/MAX31855 library - much cleaner design
