Update to .net 6.0

[PhantomGamers]

• Removes Ionic.Zip.dll in favor of using the DotNetZip nuget package
• Uses System.Text.Json instead of System.Web.Script.Serialization
• Added .editorconfig from https://github.com/dotnet/roslyn/blob/7d69096bedcf8b0b6bad5f5a493659bd46a62895/.editorconfig
• Ran Code Cleanup from VS
• Ran dotnet format style --severity info

Can be compiled into a single exe using: dotnet publish -p:PublishSingleFile=true -r win-x86 -c Release --self-contained false

Hi, this looks great, thanks for doing this!

Do you think we could remove all external dependencies by using the System.IO.Compression methods for ZipFile extraction? https://learn.microsoft.com/en-us/dotnet/api/system.io.compression.zipfile.extracttodirectory?view=net-6.0

It would be possible but it is a similar issue to switching to HttpClient in that .net's ZipFile does not provide an easy way to monitor progress like ionic's does.

I just removed the dependency on System.Text.Encoding.CodePages as it seems it is not needed.

Earlier I was getting a ''IBM437" is not a supported encoding name error, and I thought adding that solved it but I guess it was something else I changed that wound up solving it.

Now the single exe is smaller than 1.4.16 (424KB vs 1.4.16's 530KB).

(Though you should check to make sure it works on your end as well)
