Function pamoja_median_new 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_median_new() -> *mut PamojaMedian

Creates an empty median filter over PAMOJA_WINDOW_CAPACITY readings.

A median filter is what rejects a single wild reading, where an average would let it pull the answer.

Returns

A handle the caller must release with pamoja_median_free.

Safety

The returned handle must be freed exactly once.
