Fix DenseNodeIter when dense node info is empty #5

Closed nikmikov closed 4 years ago

DenseInfo might be left unpopulated by some exporters. In this case DenseNodeIter won't work. This PR is separating DenseNodeIter into DenseNodeIter and DenseNodeInfoIter

Example of such file: https://download.bbbike.org/osm/bbbike/Lausanne/Lausanne.osm.pbf

Thanks for your PR! Sorry it took so long for me to notice it. I'll try to find some time to look at the code.

Thanks again! osmformat.proto clearly states that DenseInfo is optional and I'm glad this is now reflected in the code!
