Variable name starting with UnderScore is not recognized correctly in Unity

[harayuu9]

A partial class is correctly generated in a .NET7 application using the code below, but when brought to Unity, a MEMPACK006 error is output.

Environment that does not work properly Unity 2022.3.8f1 MemoryPack 1.10.0

Environment that works properly net7.0 MemoryPack 1.10.0

[MemoryPackable]
public partial class Example
{
    [MemoryPackConstructor]
    private Example(string defaultLocale)
    {
        _defaultLocale = defaultLocale;
    }

    [MemoryPackInclude] private readonly string _defaultLocale;
}

When I checked, it seems that the content fixed in #156 is not included in Unity's Generator. Looking at the History, it seems that the version of the Generator included in Unity is quite old.

Hello. Thanks for your report. 1.20.0 has been released and support in Unity has changed to via NuGet. So I believe this issue has been resolved.
