[notready] Init before resize

[yhahn]

• Adds testcases (async + sync) for ensuring resize generates identical output when run repeatedly/at concurrency. See test only branch fail against master here: https://github.com/mapnik/node-mapnik/compare/resize-garbage-testcase?expand=1
• @springmeyer's fix by initializing the dest image

cc @springmeyer for your review

👍 Looks good to:

• Merge
• Then we can tweak package.json version from 3.4.15-hits to 3.4.16 and roll a new tag per https://github.com/mapnik/node-mapnik/blob/master/CONTRIBUTING.md
  • create new 3.4.16 milestone, assign this ticket to it
  • add changelog for 3.4.16
  • build binaries
  • kick mapnik-swoop to ensure it looks good
  • tag/publish

Going to hit the above now /cc @yhahn

Will keep branch live for now to keep npm install working.
