Fixed issues which inhibited subclassing.

ImageRow and ImageCell cannot be directly sub-classed, due to it's final modifiers.

Therefore, sub-classing needs to be done like this:
(In this case, it is, because I need a styled cell using a XIB.)

import UIKit
import Eureka
import ImageRow

public final class AvatarCell: PushSelectorCell<UIImage> {

    @IBOutlet weak var avatar: UIImageView!

    public override func update() {
        super.update()

        accessoryType = .none
        editingAccessoryView = .none

        avatar.image = row.value ?? (row as? ImageRowProtocol)?.placeholderImage
    }
}

final class AvatarRow: _ImageRow<AvatarCell>, RowType {

    required init(tag: String?) {
        super.init(tag: tag)

        cellProvider = CellProvider<AvatarCell>(nibName: String(describing: AvatarCell.self))
    }
}

A non-public ImageRowProtocol effectively prevents that.
Additionally, ImagePickerController casts row to ImageRow which we can't fulfill when overriding,
Config options are therefore ignored.
To resolve this, I introduced an ImagePickerProtocol.

Would be great, if you could merge this, so I don't have to rely on my fork.

Thanks a lot!
