20be401110 [core] CompatibilityNode: use original serialized inputs if not in graph 
renamed 'actualInputs' property to 'inputs', which returns the serialized inputs depending on whether the node belongs to a graph or not

c6531bcc7b [core] multiple trials to replace the status file to avoid file conflicts on windows 
On Windows, attempting to remove a file that is in use causes an exception to be raised. So we may need multiple trials.

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

67ac4bf2ca [core] split uids computation + cache override in updateInternals 
* add _computeUids internal method + store computed uids in a dedicated dict
* cache override:
  * add optional cacheDir parameter on updateInternal method to override graph cache directory
  * _buildCmdVars always update member variable '_cmdVars' 
  * CameraInit: ensure node does not belong to a graph and use updateInternals with temp cache directory
