Create Compiled Delegates like Setters from Getter expressions

- Any level of nesting member support (i.e. `x => x.Prop1.Prop2.Prop3`)

- Bind time error and accessibility checking. (i.e. Getters without a Setter or with a private Setter)

- NativeAOT compatible with no run-time reflection.

## Usage

> Full Sample Project: [CompiledExpressions.Sample](./CompiledExpressions.Sample)

 

1. For a library method, call `CompiledExpression.CreateAccessor` with a property/field access expression. This returns a [`CompiledAccessor`](CompiledExpressions/ComponentModel/CompiledAccessor.cs) struct with `Get(T instance)` and `Set(T instance, TValue value)` methods. The `MemberNames` property contains an array of the member names in the original expression.

```csharp

using System;

using System.Linq.Expressions;

using CompiledExpressions;

public static class Example

{

    public static void Bind(

        T target,

        Expression> targetMember

    )

    {

        var accessor = CompiledExpression.CreateAccessor(targetMember);

        

        // Get the existing value

        var value = accessor.Get(target);

        

        // Set a new value

        accessor.Set(target, value);

        

        // Get the member names

        var memberNames = accessor.MemberNames; // ["Prop1", "Prop2", "Prop3"]

        

        var memberPath = accessor.FullName; // "Prop1.Prop2.Prop3"

    }

}

```
