neuprintr v1.0

This release bumps neuprintr to v1.0. There have been a huge number of fixes and improvements since the last release. Furthermore we would now consider it a mature package; we are currently using it for analysis in a number of late stage papers and would be happy for others to do the same. You can see the full list of closed issues on GitHub.
