Avoid quadratic loop in getNumericAttributeEntropy.
We don't need to recalculate whole distribution for each split,
just move changed values. Also use array of slices instead of
map of maps of strings to avoid map overhead.
For our case I see time reductions from 100+ hours to 50 minutes.
I've added benchmark with synthetic data (iris.csv repeated 100 times)
and it also shows a nice improvement:
name old time/op new time/op delta
RandomForestFit-8 117s ± 4% 0s ± 1% -99.61% (p=0.001 n=5+10)
0 is a rounding quirk of benchstat, it should be closer to 0.5s:
name time/op
RandomForestFit-8 460ms ± 1%

Made versions of CSV-readers w/ io.ReadSeeker
...
Each method now ontains a -FromReader counterpart
such that it'll allow use of those helper-methods
even when someone does not have his data in a physical
file. The original methods make use of those -FromReader
methods.
The reader is being reset (Seek(0, 0)) before every method-
specific read, to ensure it's reading from the start of the
reader.
Test cases are not yet touched, and I'm not sure they should.
