Fix CharSegment Equals

[uselessgoddess]

CharSegment has bug in Equals method

Collections/csharp/Platform.Collections/Segments/CharSegment.cs

Lines 31 to 46 in 3643cf1

	public override bool Equals(Segment<char> other)
	{
	bool contentEqualityComparer(IList<char> left, IList<char> right)
	{
	// Base can be not an array, but still IList<char>
	if (Base is char[] baseArray && other.Base is char[] otherArray)
	{
	return baseArray.ContentEqualTo(Offset, Length, otherArray, other.Offset);
	}
	else
	{
	return left.ContentEqualTo(right);
	}
	}
	return this.EqualTo(other, contentEqualityComparer);
	}

Fix it
Small example [use this sandbox and add property PublicDictionary to Walker4]:

/*
public IDictionary<CharSegment, long> PublicDictionary
{
    get => Dictionary;
}
*/

var text = "aaaaaaaaaa";
var walker = new Walker4();
walker.WalkAll(text);
foreach (var l in walker.PublicDictionary)
{
    foreach (var r in walker.PublicDictionary)
    {
        Console.WriteLine($"{l} == {r} ==> {l.Key.Equals(r.Key)}");
    }
}
