    Hello !

    Thinking about a better mzML to store proteomics data, but not convinced by the approach, I've converted it into :
    * Smaller data files (only 66% of the mzML original file) for the exact same data
    * Faster to read (25s for a big mzML vs 18s in mzcbor on the same computer)
    * Very quick random access to spectra (24.6577 ms for mzML vs 786.731 μs for mzcbor for the same operation using index)

    I'd like to share it if you are interested at
