Make the _options field protected instead of private

[gsandorx]

I had to extend the SieveProcessor class via inheritance. I overwrote the MapProperties method in my class and needed to read the configuration (through Options). However, this is not accessible.

public class MySieveProcessor 
{
       public IOptions<SieveOptions> Options { get; private set; }
 
       public MySieveProcessor(
            IOptions<SieveOptions> options)
            : base(options)
        {
            Options = options;
        }

       protected override SievePropertyMapper MapProperties(SievePropertyMapper mapper)
       {
               // I need to read the configuration here. However, this method gets called by the base class, meaning that I can't even 
               // use my own Options property because it hasn't reached that line in my constructor yet. And the base SieveProcessor
               // _options member is private
       }
}

I don't see any downsides to make Options property protected. I'll change the MapProperties method call place, though.
