How to upload and download wiki attachments?

[mmokross]

At least I couldn't find a way to upload and download attachments.

• I'm not sure if \Gitlab\Api\Projects::uploadFile could be used to upload, because in the url there is not the /wikis/ path
• \Gitlab\Api\Wiki::show can't be used to download, because I can't add the necessary path - for example uploads/3a857cdc4e2f2d84c3d94a7ecf316b28/image.png - , which would by modifed by \rawurlencode
