Add <distributionManagement> preemptively

The next bump to our parent will introduce a new distributionManagement
section intended to deploy to OSS Sonatype. We are not ready for that yet,
though, so make sure that we continue to deploy to ImageJ's Maven
repositories.
Bump to pom-scijava-132

Increased the pom-scijava version to the latest. This includes an update
to SCIFIO-0.9.2 with several breaking changes.

Updated API and tests as appropriate for the latest API.
