Structure of the pre-histogrammed Image Data File

Data Item				Type	Description
PixX				`int32`	pixels in X-direction
PixY				`int32`	pixels in Y-direction
PixResol				`float32`	spatial pixel resolution in μm
TCSPCChannels				`int32`	number of TCSPC channels per pixel
TimeResol				`float32`	time resolution of the TCSPC histograms in ns
The following block will appear in the file for each `y = 1 to <PixY>`
	The following block will appear in block (y) for each `x = 1 to <PixX>`
		The following data will appear in the block (x,y) for each `t = 1 to <TCSPCChannels>`
			`HistogramData [x,y,t]`	`int32`	counts of the TCSPC channel t of pixel (x,y)
