Update on Optking, a molecular geometry optimizer

From a channel Lumen includes in full: This is the official Psi4 project channel. It consists of software tutorials (installation, input/output structure, optimizations, frequencies, Python API) and expert conference or workshop talks on quantum chemistry methods and teaching labs. Every sampled transcript is technical instruction or a technical expert talk, with no entertainment, hype, or clickbait. The only marginal item, a community-logistics talk on contributing, is excluded by title pattern.
