export_imzMLpeakList: export_imzMLpeakList.
In prafols/rMSIproc: MSI Processing in C++

Export an rMSIproc peak list as an imzML processed dataset.

export_imzMLpeakList(
  peakList,
  posMatrix,
  pixel_size_um,
  filename,
  normalization = rep(1, length(peakList))
)

`peakList`	an rMSIproc peak list object.
`posMatrix`	an rMSI pos matrix with the pixel coordinates in the image.
`pixel_size_um`	the image pixel size in microns.
`filename`	complete path where the imzML and ibd files will be stored (the .imzML extensions must be omited).
`normalizations`	a numeric vector contaning the normalization value for each pixel (1 by default).
