// skate-reduce takes prepared inputs (e.g. from skate-map or skate-cluster)
// and applies various verification and conversion functions. The output will
// often be the biblioref schema.
//
// Support various modes.
//
// * exact: takes (key, doc) TSV files (one for releases, one for refs) and
// will emit biblioref docs relating one element from releases with all
// elements from ref; this is for "doi", "pmid" and other id matches, where no
// further checks are necessary. The match reason, e.g. "doi" needs to be
// supplied.
//
// $ skate-reduce -m exact -r doi -F a.tsv -L b.tsv
//
// * verify: takes (key, doc) TSV files (one for release, one for refs), runs
// verification within a group and will emit biblioref.
//
// $ skate-reduce -m verify -F a.tsv -L b.tsv
//
// * ref: takes a single file with clusters containing releases and refs and
// will emit verification results.
//
// $ skate-reduce -m ref < a.ndj
//
// * bref: same as ref, but generate a biblioref file as output
//
// $ skate-reduce -m bref < a.ndj
//
// * wiki: zippy mode for releases and wikipedia inputs.
//
// $ skate-reduce -m wiki -L a.ndj -W b.ndj
