• @param {Object<number=>any>} tests with names
• @param {number} [POOL_MS=50*minMS] nominal duration of each pooled sample to compensate for system precision rounding
• @param {number} [Q1_PAD=3] dropped min & max sample at each tail
• @returns {Array} IQR of the test ops/sec (Hz)

Ideas

• pooled tests to get a minimum ms per run to compensate for the 1ms timer rounding in browsers
• use the more stable quartiles (25%, 50%, 75%) instead of averages, errors, significance, tests and all (median of means)
• tests are interleaved (a,b,c, b,c,a, ...) 4*Q1_PAD+1 times (default 13 times)
• use the type returned by function and enforce that they stay the same
• 1 initiation + 4*Q1_PAD+1 samples per tests
• works in node and in browsers
• tests returning a thenable are treated as async
• each test function is run with a counter 0..n as argument
