/**
* @brief Determines the unprintable filaments for each extruder based on its physical attributes
*
* Currently, the criteria for determining unprintable filament include the following:
* 1. TPU filaments can only be placed in the master extruder and must be grouped alone.
* 2. We only support at most 1 tpu filament.
* 3. An extruder can only accommodate filament with a hardness requirement lower than that of its nozzle.
* If extruder num is 1, just return an empty vector.
*
* @param used_filaments Totally used filaments when slicing
* @param config Config that stores releted params
* @return A vector of sets representing unprintable filaments for each extruder
