coreclr node

> This is a very early release of this package, do not suggest using it in production till latter stable version

Add the CoreclrNodeHost reference to the csproj config
``xml

`

create an example c# entry class
`csharp
namespace BasicExample
{
using System;
using FluentAssertions;
using System.Threading.Tasks;
using CoreclrNodeHost;
using CoreclrNodeHost.InProcess;

public class Program
{

private static readonly TaskCompletionSource MainTaskCompletionSource = new TaskCompletionSource();

public static JsDynamicObject setMainTcs(JsValue[] args)
{

Console.WriteLine($"Basic example setMainTcs invoked w/o {args.Length} arguments");

var host = NodeHost.Instance;

args.Length.Should().Be(4);

host.TryGetObject(args[0], typeof(bool), out var oneBool);
oneBool.Should().Be(true);

host.TryGetObject(args[1], typeof(double), out var oneNumber);
oneNumber.Should().Be(1e3);

host.TryGetObject(args[2], typeof(string), out var oneString);
oneString.Should().Be("oneString");

host.TryGetObject(args[3], typeof(Object), out dynamic oneObj);
// oneObj.Should().BeOfType(typeof(JsDynamicObject));
((string) oneObj.message).Should().Be("oneMessageStringInObj");

var result = host.New();
host.SetMember(result, "argCount", DotNetValue.FromInt(args.Length));
host.SetMember(result, "message", DotNetValue.FromString("oneMessageStringInResultObj"));

MainTaskCompletionSource.SetResult(0);

return result;
}

public static Task Main(string[] args)
{
Console.WriteLine($"Basic example entry invoked {args[0]}");

return MainTaskCompletionSource.Task;
}
}
}
`

then invoke the static method from javascript
`javascript
const assert = require('assert');
const path = require('path');
const coreclrhost = require('@albertli90/coreclr-host');

const result = coreclrhost.runCoreApp(
path.join(__dirname, 'bin', 'Debug', 'netcoreapp3.1', 'BasicExample.dll'),
"AdditionalArgument"
);

const setMainTcsResult = coreclrhost.callManagedFunction(
"BasicExample.Program",
"setMainTcs",
true,
1e3,
"oneString",
{
message: "oneMessageStringInObj"
}
)

assert.strictEqual(typeof setMainTcsResult, "object");
assert.strictEqual(setMainTcsResult.argCount, 4);
assert.strictEqual(setMainTcsResult.message, "oneMessageStringInResultObj");


(async ()=>{
assert.strictEqual(await result, 0);
})()
