* Migration to PlatformIO 6.1.0 * Disable RMTMEM usage as it is no longer allowed -> Smart LEDs not functional! * moved miniz into subfolder of jomjol_fileserver_ota, else it does not build anymore. * cleanup * fix leading NaN (#2310) * Migration to PlatformIO 6.1.0 * Disable RMTMEM usage as it is no longer allowed -> Smart LEDs not functional! * moved miniz into subfolder of jomjol_fileserver_ota, else it does not build anymore. * cleanup * Task watchdog has new config name * Fix return value check. It must be something else than ESP_FAIL, but it does not need to be ESP_OK! * add missing strucures to work around new RMTMEM restriction (untested) --------- Co-authored-by: CaCO3 <caco@ruinelli.ch>

As a dirty workaround, we copy the needed structures from rmt_struct.h

In the long run, this should be replaced! */
