Swifterswift: Add KeyedDecodingContainer extensions

[omaralbeik]

Add the following extensions to KeyedDecodingContainer

public extension KeyedDecodingContainer where Key: CodingKey {
    /// SwifterSwift: Try to decode a Bool as Int then String before decoding as Bool.
    ///
    /// - Parameter key: Key.
    /// - Returns: Decoded Bool value.
    /// - Throws: Decoding error.
    public func decodeBoolAsIntOrString(forKey key: K) throws -> Bool { ... }

    /// SwifterSwift: Try to decode a Bool as Int then String before decoding as Bool if present.
    ///
    /// - Parameter key: Key.
    /// - Returns: Decoded Bool value.
    /// - Throws: Decoding error.
    public func decodeBoolAsIntOrStringIfPresent(forKey key: K) throws -> Bool? { ... }
}
