LUCENE-8174: Fixed toString method of (Double|Float|Int|Long)Range classes.
The previous implementation produced an ArrayOutOfBoundsException because of an
incorrect calculation of the dimension index.
Also, the ranges for each dimension were never appended to the StringBuilder at
all (which, however, could not actually be observed due to the exception).

> Key: LUCENE-8174
> URL: https://issues.apache.org/jira/browse/LUCENE-8174
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/index
> Affects Versions: 7.2
> Reporter: Oliver Kaleske
> Priority: Major
> Attachments: LUCENE-8174.patch

>
> The following code produces an ArrayIndexOutOfBoundsException:
> {{ IntRange intRange = new IntRange("foo", new int[] \{ 1 }, new int[]
> \{ 2 });}}
> {{ System.out.println(intRange.toString());}}
> The exception is thrown in NumericUtils.sortableBytesToInt, which is fed an
> incorrect offset.
> The bug appears to be in IntRange.toString. I guess the for loop should read
> {{for (int d=0; d<type.pointDimensionCount()/2; ++d)}}
> instead of
> {{for (int d=1; d<type.pointDimensionCount(); ++d)}}
> because the number of dimensions is half the number of "point dimensions"
> (cf. the checks on the dimension parameter in getMin() and getMax()).
> The same bug is found in the DoubleRange, FloatRange, and LongRange classes.
