v1.74.3

-- Sync with latest shared libraries

* DataTree, v1.8.1
-- Fix error when trying to retrieve ppf param during image recon because dataTree.currElem.procStream.fcalls being empty. This is because of using GroupClass.CompareVersions caused procstream fcalls from groupResults not to load (it was deemed too old) which is clearly not what we want. Removed for now the comparison (CompareVersions for now always returns 0)  until we can figure out best way to handle old versions of groupResults.
-- Provide ProbeClass.GetScaleFactor() method to retrieve private scaling field
-- In ExportProcStreamDependencies get rid of the *_Library_Version suffix next to each library name in the JSON output

* FuncRegistry, v1.2.2
-- Fix issue with converting mlACt vector to 2D array with mlAct_Initialize.m during image recon.

* Utils, v1.3.2
-- Add ability to versionstr2num to process version arguments in the form of 3 numbers rather than a string for backward compatability with DataTree GroupClass to get old style version.
