For cases where a node declares a size that is bigger than it actually is, the start of ranges might exceed the number of views in the SfMData. Instead of causing an EXIT_FAILURE, we detect that the size of the range is incorrect to proceed with computations, and return EXIT_SUCCESS. This allows to use nodes such as the `KeyframeSelection`, for which the number of outputs can rarely be known before the end of the computations: if the number of chunks for `PrepareDenseScene` and `FeatureExtraction` is too large for the actual size of `KeyframeSelection`, then we keep on going through the pipeline instead of failing.

Description
Related Meshroom pull request: alicevision/Meshroom#2039
This PR changes the behaviour of nodes with chunks that check the validity of the ranges they are provided with. Instead of causing an
EXIT_FAILUREwhen the starting point of the range exceeds the number of views in the SfMData, we detect whether the size of the range with this starting point is negative (which means that the chunks were created based on erroneous information), and skip the computations before returningEXIT_SUCCESS.This allows to use chunks after nodes whose announced size does not always correspond to the reality, because their number of outputs cannot be precisely determined before their computation.
This PR affects the
PrepareDenseSceneandFeatureExtractionexecutables.
