Dean Michael Berris f81b08001a [XRay] Refactor loadTraceFile(...) into two (NFC)
This patch splits the file trace loading function into two versions, one
that takes a filename and one that takes a `DataExtractor`.

This change is a precursor to larger changes to increase test coverage
for the trace loading implementation.
