Converts a numpy array from raw segy trace data to native floats. Works for numpy ndarrays.
Examples:
Convert mmap'd trace to native float:
>>> d = np.memmap('file.sgy', offset = 3600, dtype = np.uintc)
>>> samples = 1500
>>> trace = segyio.tools.native(d[240:240+samples])

Parameters
----------
data : numpy.ndarray
