Convert decimal strings with comma separator

[pz1337]

Expected behavior

The class SwapStringToBytes can convert strings declared as decimal with a comma as decimal separator to doubles. (See test code below.)
The class SwapStringToBytes has a test class SwapStringToBytesTests.
The class SwapStringToBytes is in the namespace PAQO.Core.Facets.
The class SwapBytesToString is in the namespace PAQO.Core.Facets.
The class SwapBytesToStringTests is in the namespace PAQO.Core.Facets.Test.

Actual behavior

The class SwapStringToBytes cannot convert strings declared as decimal with a comma as decimal separator to doubles.
The class SwapStringToBytes has no test class.
The namespaces are wrong.

Steps to reproduce the behavior

using PAQO.Core.Prop;
using Xunit;

namespace PAQO.Core.Facets.Test
{
    public sealed class SwapStringToBytesTests
    {
        [Fact]
        public void DeliversDoubleForCommaDecimalSeparator()
        {
            Assert.Equal(
                6083.15,
                new DecimalProp.AsDouble(
                    new SwapStringToBytes().Flip("decimal", "6083,15")
                ).Value()
            );
        }
    }
}

The log given by the failure.

I see two possible solutions to this problem.

1. Provide a CultureInfo to class SwapStringToBytes which is used to parse numerical values.
2. It's the app reponsibilitiy to transform the numeric value into a Culture Invariant format which is used by PAQO to parse numeric values from string.

The first approach is my personal favorit.
