feat(scancode): Support reading matched_text fields

When ScanCode is run with `--license-text`, `matched_text` fields are
added to license findings that contain the matched license text. Support
reading those fields even if they are not used yet. This enables
programmatic use of those fields and / or future use e.g. when
deserializing ScanCode results from ClearlyDefined (which runs ScanCode
with `--license-text`).
