P: Add manual lens correction tools

Hello. LR Desktop is getting so close to being at parity for editing features with LR Classic! One thing that is still missing though is a manual option for lens corrections. Currently, if there is no matching profile for your lens, you cannot resort to correcting distortion and vignetting manually like you can in LR Classic and ACR. The vignette tools in the Effects tab or not an adequate substitute for manual vignette correction - they seem to work differently than the manual vignette correction tools found in LR Classic and ACR and do not produce the same results. Please add these lens correction tools back to LR Cloud!
