BUG Account for other Possible unpickling errors

[gadorlhiac]

Description

This PR provides additional error handling in the PipeCommunicator.read method to account for other types of exceptions that can arise during unpickling.

Checklist

• Catch ValueError and EOFError when attempting to unpickle a potentially encoded, or mixed pickle/encoded, bytes object.
• Allow the PipeCommunicator to re-enable using pickle by default.

PR Type:

• New feature/Enhancement

Address issues:

• NA

Testing

Tested against the psocake peak finding Task (merged earlier today) where this potential failure mode was discovered. The Task printed the message: b'Found an event with image: 0\nfindPeaks: exp=cxic0515:run=0009:idx\n' which produced an uncaught ValueError and caused failure. The temporary fix was to comment out the line of code allowing the PipeCommunicator to set _use_pickle back to True.

The fixes introduced in this PR address the issue. The Task runs without error even with the temporary fix removed by uncommenting.

The PR can be tested by running: /sdf/scratch/users/d/dorlhiac/script_psocake.sh which points to an installation of LUTE checked out to this branch.
