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

plot the ion image map of a given mass or column of a rMSIproc peak matrix object. If the peak matrix contains data from various datasets the images will be layout horizontally or vertically. At leas mz or column must be specified.

`peakMatrix`	the peak matrix in an rMSIproc object.
`mz`	the peak mass to plot, the nearest peak mass will be ploted.
`column`	the column of the peak matrix to plot.
`matrix`	the name of the peak matrix to plot.
`normalization`	the name of normalization to use.
`nrow`	number of rows of the plotted matrix layout (only used if byrow == F)
`ncol`	number of cols of the plotted matrix layout (only used if byrow == T)
`byrow`	a bool specifing if images must be arranged in rows.
`margin`	the separation between plotted images.
`img_names`	a character vector with img names in the desierd plotting order.
`labels`	an alternative character vector with the labels to be displayed for each image.
`rotations`	a vector with the rotation of each images specified in degrees.
`mirror_x`	a bool vector specifing if each image must be flipped or not in X direction prior to rotation.
`mirror_y`	a bool vector specifing if each image must be flipped or not in Y direction prior to rotation.
`pixel_size_um`	the pixel resolution in um.
`light`	the lighting of the plotted image.
