* Removed the dependency to the private `R2LCPClient.framework`, which means:
    * Now `r2-lcp-swift` works as a Carthage dependency, no need to use a submodule anymore.
    * You do not need to modify `r2-lcp-swift`'s `Cartfile` anymore to add the private `liblcp` dependency.
    * However, you must provide a facade to `LCPService` (see README for an example implementation).
