Validator: duplicate nodes test should round to OSM precision

Description

When a node having a very precise coordinate is uploaded to OSM, it looses some of the precision. When it is later downloaded from OSM, and a non-uploaded node is merged into the layer, the duplicate nodes test fails to pick this up.

For instance:

  • New node: 50.8657084066, 5.67127850237
  • Upload this to OSM, and then later download
  • It's now: 50.8657084, 5.6712785
  • Merge in more of the original dataset
  • Run the validator. It (rightfully) fails to see these as duplicate nodes, because they are not exactly alike.

I propose to round off any coordinates to the maximum OSM precision, when running the duplicate nodes test. These more precise node coordinates will be rounded anyway, when they're uploaded.
