[client-v2] Impossible to get float value by getFloat() because of incorrect overflow check

[chernser]

Describe the bug

If reader attempts to call getFloat() on a column of Float64 type and value fits float it still gets exception about overflow:

java.lang.ArithmeticException: float overflow: 1.1 cannot be presented as float

This happens because of this overflow check:

                 Number number = (Number) value;
                 if (number.floatValue() == number.doubleValue()) {
                    return number.floatValue();
                } else {
                    throw new ArithmeticException("float overflow: " + value + " cannot be presented as float");
                }

Obviously double value might have some "noise" fraction:

public void testCompareFloatAndDouble() {
        float f = 1.1f;
        double d = 1.1d;

        Assert.assertEquals(f, d);
    }

Output:

java.lang.AssertionError:
Expected :1.1
Actual   :1.100000023841858

The overflow check might be too complex from performance stand point, so this PR removes check for float and double.
