GPIOFile direction being ignored

[DanielSSilva]

Taking into consideration this code _ButtonGPIO = new GPIOFile((GPIOPins)GPIOPin, GPIODirection.In); When this code runs, doing less /sys/class/gpio/gpio10/direction (10 because it's the value of the GPIOPin variable) returns Out. The problem here is that the constructor referred above calls the public GPIOFile(GPIOPins pin, GPIODirection direction, bool initialValue) with false on the initialValue parameter. This one calls the base with: our pin, GPIODirection.In, false. The code for setting the PinDirection is the following

PinDirection = direction;
Write(initialValue);

and the Write method is (partially) defined as this:

        PinDirection = GPIODirection.Out;```

This setting will ALWAYS override the direction set.

My suggestion is that there should be another constructor on the `public abstract class GPIO : IDisposable`
I can try and contribute for that, but for that I would like you to DM me so that I can understand the process :)
