Possible bug with forced casting on IChannelPerceptualHash

[Gounlaf]

Magick.NET version

13.6.0 (since 0fcf386)

Environment (Operating system, version and so on)

All

Description

Since commit 0fcf386, ChannelPerceptualHash.SumSquaredDistance force casting of parameter IChannelPerceptualHash to implementation ChannelPerceptualHash :

Magick.NET/src/Magick.NET/Statistics/ChannelPerceptualHash.cs

Lines 97 to 104 in 0fcf386

	public double SumSquaredDistance(IChannelPerceptualHash other)
	{
	Throw.IfNull(nameof(other), other);
	var otherChannelPerceptualHash = other as ChannelPerceptualHash;
	var ssd = 0.0;
	foreach (var huPhashList in _huPhashes)

It breaks interface contract.

I don't have a solution to suggest =/

Regards.

Not doing the cast would force me to expose the HuPhashList that nobody will want to use. So I took this shortcut. Creating an interface for the HuPhashList is probably a better solution. I will take a look at this next week.
