 * Convert a benchmark unit string to a metric name suitable for use as an
 * object key.
 *
 * Known aliases take precedence over the general rule:
 *   "B/op"    -> "bytes_per_op"
 *   "MB/s"    -> "mb_per_s"
 *   "ns/iter" -> "ns_per_iter"
 *
 * General rule: replace every `/` with `_per_`, replace spaces with `_`,
 * then lowercase.
