TryConvertFromChecked check will never pass

[pipman3000-rettata]

From my testing in .NET 9, this IsAssignableTo call in the TryConvertFromChecked function will never return true:

Singulink.Numerics.BigDecimal/Source/Singulink.Numerics.BigDecimal/BigDecimal.GenericMath.cs

Lines 85 to 92 in 81eb66a

	else if (typeof(TOther).IsAssignableTo(typeof(IBinaryInteger<>)))
	{
	if (TOther.TryConvertToChecked<BigInteger>(value, out var intValue))
	{
	result = (BigDecimal)intValue;
	return true;
	}
	}

It doesn't work with any of the built-in types, including BigInteger. I believe this has something to do with parameterless generic types being considered a completely different type under the hood than one with a defined parameter.

I don't think there's a solution that would be better than just removing that check completely and simply attempting to convert to BigInteger right off the bat.
