Changed
Major upgrade. The extraction performance drastically improved (~100 times).
Vertical stacking of parameters. The sections are now maps of parameters.
Parameters are converted to lists of numpy arrays, stored as bytes.
The packing of bytes is 100 times faster than the packing of lists of lists.
Concatenation of parameters accross of sections is done using list.extend(),
this is 6 times faster than using numpy concatenation.
The iteration speed during extraction reaches 1000 MB/s (tested with
1.3 GB file test_1200_MBPS.aps).
