CSV files read issues

[pomadchin]

It looks like we're requesting points not generic enough / things had changed a bit since 1.4.

Add a unit test to read the following CSV file:

X,Y,Z,TEST
289814.150,4320978.610,170.760,2.000
289814.640,4320978.840,170.760,2.000
289815.120,4320979.060,170.750,2.000
289815.600,4320979.280,170.740,2.000
289816.080,4320979.500,170.680,2.000
289816.560,4320979.710,170.660,2.000
289817.030,4320979.920,170.630,2.000
289817.530,4320980.160,170.620,2.000
289818.010,4320980.380,170.610,2.000
289818.500,4320980.590,170.580,2.000

We can get access to the point if here we'll use pl->dimTypes() call instead.

So we store a bit incorrect information in JVM memory.
