Allows corrupted Tracking Data Directory to be opened / fixed from fort-studio / fort-myrmidon

[atuleu]

Is your feature request related to a problem? Please describe.
With the FORT system, it may quite often happens that a tracking data directory becomes corrupted... Indeed, often user ran out of disk space during acquisition

Describe the solution you'd like
When opening a tracking data directory, any error should be reported with exception that allow the error to be fixed by modifying the data. fort-studio could display these error / fixes and allow the user to react accordingly.

Tasks

• Create a fort::myrmidon::FixableError public exception. It should describe the problem, describe the fix, and implement the fix
• Makes priv::TrackingDataDirectory to softly ignore FixableError, but return them. It means, it should try to open every TagCloseUp, but do not do so already
• Makes fort::myrmidon::Experiment::TrackingDataDirectory return a list of fixable error
