pointcloud converter: XYZ format, error if R G B values are floats

[unitycoder]

this works, RGB values are integers
2.66090000 1.22850000 1.69810000 255 255 255
3.64860000 1.56760000 2.30120000 251 247 251
3.64610000 1.55790000 2.29770000 254 254 255
3.64650000 1.54950000 2.29600000 250 252 250

this doesnt, RGB values are floats/doubles
2.66090000 1.22850000 1.69810000 254.99 253.3 253.3
3.64860000 1.56760000 2.30120000 251.123 247.2 251.5
3.64610000 1.55790000 2.29770000 254.3 254.1 255.4
3.64650000 1.54950000 2.29600000 250.03 252.5 250.2

in the next update i'll add convert to int for RGB values.

actually not fixing that, would add extra checks and conversions from floats.. (since they should be ints normally)
