Do not compile with Carthage or SPM

[mamcx]

I create a new project with Swift 4 & XCode Version 9.2.

I try using Carthage and after the build it not show SwiftLMDB.framework anywhere.

Then, I try to use https://swift.org/package-manager/, it get fetched ok but get:

/.build/checkouts/SwiftLMDB.git-2506504943730548242/Sources/DataConvertible.swift:243:33: 'dataRepresentation' is only available on OS X 10.11 or newer
/.build/checkouts/SwiftLMDB.git-2506504943730548242/Sources/DataConvertible.swift:236:25: 'init(dataRepresentation:relativeTo:isAbsolute:)' is only available on OS X 10.11 or newer

The deployment target is set to OS X 10.11 and Base SDK is 10.13

Hi!

This package has never been tested with Carthage. You are welcome to create the necessary changes (if any) and submit a pull request. Otherwise you will need to use Swift Package Manager.

I would bump up the deployment target but it appears that there is no way of doing so in the Package.swift file. Introducing xcconfigs seems messy. Instead, I've removed the offending code. If you are running macOS 10.11 or later, you can add the URL conformance to DataConvertible yourself in an extension. Try building the latest tag.
