Recommendation for an iPad Pro SD card reader

Greetings everyone, does anyone on this forum use an iPad Pro to post-process raw digital image files? I bought a 128GB wi-fi only iPad Pro when it came out last month and I love it. I didn't buy it to work on my photos, but after receiving it, I think it would be great for that purpose. I shoot with a Sony a6000 mirrorless camera. I was looking online for SD card readers and it looks like there's not much out yet for the iPad Pro and Apple's standard card reader doesn't appear to get good ratings. If possible, I would like to import raw image files from my camera's SD card on my iPad Pro, then export the edited jpeg files and the original raw image files to my desktop Mac for archival purposes. Is this possible? Which card reader would work best this purpose?
