Export Spectra as HDF5 format (.h5)?

[Don86]

Hi,

I'd like to ask if there's currently a way to write out a Spectra S4 object, probably initially read as .mzML or .mzXML, as .h5? There doesn't seem to be this capability from what I'm seen in the manual. HDF5 seems like a better storage option since it has a smaller file size, well-supported outside of the mass spec world, and easily-interoperable with Python as well.

Regards, Don
