Serialize a spectra and/or chromatogram mzML file

This class will serialize a spectra and/or chromatogram mzML file and store it in a binary format that contains ONLY the spectra and chromatogram data (no metadata).

This is implemented using the write_memdump and read_memdump functions. For reading there are 2 options

read the whole file into the OpenMS datastructures
read only an index (read_memdump_idx) of the spectra and chromatograms and then use random-access to retrieve a specific spectra from the disk (read_memdump_spectra)

Note: This tool is experimental!

The command line parameters of this tool are:

Usage:
  OpenSwathMzMLFileCacher <options>

Options (mandatory options marked with '*'):
  -in <file>*                Input mzML file (valid formats: 'mzML', 'sqMass')
  -in_type <type>            Input file type -- default: determined from file extension or content
                              (valid: 'mzML', 'sqMass')
  -out <file>*               Output file (valid formats: 'mzML', 'sqMass')
  -out_type <type>           Output file type -- default: determined from file extension or content
                             Note: that not all conversion paths work or make sense. (valid: 'mzML', 'sqMass'
                             )
  -convert_back              Convert back to mzML
  -lossy_compression <type>  Use numpress compression to achieve optimally small file size (attention: may 
                             cause small loss of precision; only for mzML data). (default: 'true') (valid: 
                             'true', 'false')
  -full_meta <type>          Write full meta information into sqMass file (may require large amounts of memor
                             y) (default: 'true') (valid: 'true', 'false')
                             
Common UTIL options:
  -ini <file>                Use the given TOPP INI file
  -threads <n>               Sets the number of threads allowed to be used by the TOPP tool (default: '1')
  -write_ini <file>          Writes the default configuration file
  --help                     Shows options
  --helphelp                 Shows all options (including advanced)
