Its not enough to declare "doc" as DynamicJsonPSRAMDocument - PSRAM is not yet initialized when "doc" is created. So we need a trick to get the main doc into PSRAM later, during WLED::setup().
Code is very experimental, may or may not work, and need more testing

if random palette was used in the startup preset, all LEDs were orange until the first palette cycling happened.
This fix ensures that there is no all-orange palette initially.
According to the technical manual, GPIO 16 + 17 are used for onboard flash, so cannot be used by WLED.
example buildenv:
[env:esp32_pico]
extends = env:esp32dev_qio80
board = pico32
I've found a code spellchecker, so this is what can be corrected easily. Changes are only affecting comments, readme and a few user-visible strings. So no functional impact expected.
we can use `-D CONFIG_ASYNC_TCP_TASK_STACK_SIZE=xxxx` to increase the stack size of AsyncWebserver - default is 8196.
This should give us a bit of headroom for new UI items.
We still need PR #94 for more savings.
Found out that the main JSON 'doc' is still living in normal RAM, even when PSRAM is available...
This results is very low RAM especially on -S2.
This change tries to find a balance between "need large json buffer" and "other features become unstable when free RAM is low".
* fix some too-long tabs
*author info added
* shrunk number of blank lines
* removed unused audio variables
* colorIndex : better accuracy by first doing multiply, then divide
Some usermods may cause unexpected behaviour if not configured properly.
* Battery: can cause unexpected shutdowns if no voltage measurement circuit connected
* RTC: can cause unexpected time &date changes if no RTC connected to I2C
* mcu temp: can cause hight CPU load, and may cause instabilities due to use of an "unsupported" API from espressif
