Resolve each dataset's source_accessed: the ingest's own stamp, else git

Reads metadata.json sources[] (written by build_metadata_json() from stamp_source_access()) and takes the newest stamp; where an ingest has none, falls back to source_accessed_from_git().

Usage

resolve_source_accessed(dir_parquet)

Arguments

dir_parquet

one or more sidecar directories (data/parquet/{provider}_{dataset})

Value

As source_accessed_from_git().
