Description
Basically this would be:
scale.invert = x => d3.least(domain, value => Math.abs(scale(value) + scale.bandwidth/2 - x))
(could be useful with #1629, for example)

Research direction
Start by locating the point and band scale implementations and checking how scale inversion is handled elsewhere in the repository. Review the proposed d3.least-based behavior and the relationship to #1629. Done would require a decided API and verified inversion behavior for both scale types, but the issue does not name files or tests.
