Extreme zoom values do not work as expected
The upper limit of the zoom parameter is not accepted as it is, but incremented by about 0.5 by Root:
./HexPlot -i ../examples/test_data.txt -g ../geo/hex_positions_HPK_128ch_6inch.txt -o ../examples/example.pdf -IV -p HEX -pn 1 -select 10 -ys 1e-1 -ap 0 -z 52:53
The plot has a z-axis from 52 to 53.5
