High Quality Market (HQM) corporate bond yield curve - full curve in one call

The full HQM corporate-bond yield curve (FRED release 402): ~100 maturity points (0.5yr..100yr) for the requested date(s). Returns the WHOLE curve from ONE release-table call per date - the production-safe replacement for the ~200 single-series fetches the generic proxy would need. yield_curve selects spot (element 219299) or par (219294). Rate is a decimal fraction (2.5% -> 0.025).
