There are many threads for this. I will resume the easiest solution (I personally use it). Buy X-Transformer for Windows from Iridient, it's really cheap and it doesn't change the workflow that much.
1) convert your RAF with this tool
2) import the DNG results into Lightroom
3) work with Lightroom as usual (apply film simulation if you want)
Some subject/pattern are less affected by this pattern so I don't use the tool for all images.
The tool can be also used as a Lightroom external editor. In that case, you import your RAF, and you convert from Lightroom, it's even easier but requires minor configuration.
