Parse should be included as a peerDependency to avoid configuration conflicts in implementing projects

[beau6183]

Parse is already bundled with parse-server. Since this is an extension for parse-server, it should not include parse itself, but instead expect it as a peerDependencies item. This is important to avoid situations where configuration for parse can get lost due to multiple included libraries including parse in their dependencies list.
