 * Perform a partial pre-merge of bidder config for PBS.

 * a bidder-specific array will replace a global array.
 *
 * This returns bidder config (from `bidder`) where arrays are replaced with what you get from merging them with `global`,
 * so that the result of merging in PBS is the same as in JS.
