Support for ESP32-S2 Logic Board

To compile for the S2 version in PIO, use the following under your platform_override.ini - keep in mind that the pins have been defined for my purple lolin_S2 type of board (easy to get from AliExpress, very common and cheap), your board may have a different pin arrangement and memory (flash and PS) so check and adapt accordingly:

[env:lolin_s2_mini]
platform = https://github.com/tasmota/platform-espressif32/releases/download/2023.02.00/platform-espressif32.zip
board = lolin_s2_mini
board_build.f_flash = 80000000L
board_build.flash_mode = qio    ; reports dio anyhow
upload_speed =  460800 ;921600
board_build.partitions = tools/WLED_ESP32_4MB_1MB_FS.csv

  -D USE_ALT_DISPLAY ;; four line display seems to have problems with I2C - it hangs during usermod setup
  -D USERMOD_FOUR_LINE_DISPLAY ;; see above
  -D USERMOD_ROTARY_ENCODER_UI ;; see above

lib_deps = ${esp32s2.lib_deps}
  https://github.com/blazoncek/arduinoFFT.git ; Needed for Audioreactive Mod on S2 S3 variants due to lack of FPU
lib_ignore = IRremoteESP8266 ; use with WLED_DISABLE_INFRARED for faster compilation

Also, the above build will support the digital I2S input using the INMP441.
