Given Spinnaker is a non-JLL managed dependency, it is sometimes helpful to delay the lib init
so that julia has preference over which libraries are loaded, to avoid Spinnaker loading deps that are incompatible with JLL-provided libs
Like this one, from loading VideoIO

The simple way to do this is to load Spinnaker before other packages.
However, if Spinnaker is in a sysimage and thus has its __init__() called on julia load, this PR is needed so you can delay the lib init by setting env var JULIA_SPINNAKER_MANUAL_INIT to "true" and loading julia packages before calling Spinnaker.init() manually.
