ae716602ab [core] update nodes topological data after nodes status update

30cd8001fd [core][graph] update nodes computability on topology change 
CompatibilityNodes introduce a new notion of computability per node.
An uncomputed (and therefore uncomputable) CompatibilityNode blocks the computation of all its successor.

* update nodes computability on topology change (in addition to min/max depth)
* evaluate leaves computability to determine if the whole graph can be processed

33eb7f3a7f [core] introduce CompatibilityNode for improved scene compatibilities 
Improve node serialization/deserialization to be able to recreate the exact same node in the graph when loading a meshroom project, even if the corresponding node's description has changed or does not exist anymore. This allows to recover already computed data on disk, without being impacted by changed uids. CompatibilityNode also provides an on-demand upgrade system to turn into a Node that meets the current node description (if possible).
 
* new abstract class BaseNode, base class for Node and CompatibiliyNode 
* Node: serialize everything needed to spawn a CompatibilityNode with precomputed outputs: inputs, uids, parallelization settings, unresolved internal folders and outputs
* node_factory: handles node deserialization and compatibility issues to create either a Node or a CompatibilityNode
* add compatibility unit tests

   * meshroom release 
   * file format
   * node types used in the graph
* save the graph in a dedicated "graph" category
* multiview: store pipeline version in graph header
