 * Hack to enable overriding benchmark arguments (since we can't easily do this in CI, per apk)

 * The *correct* way to do this would be to put the following in benchmark/build.gradle:
 *
 * ```
 * android {
 *     defaultConfig {
 *         testInstrumentationRunnerArgument 'androidx.benchmark.suppressErrors',
 *                 'CODE-COVERAGE,DEBUGGABLE,EMULATOR,LOW-BATTERY,UNLOCKED'
 *     }
