setup r3 router benchmark

[c9s]

This PR setups a router benchmark for php-r3 http://github.com/c9s/php-r3

Worst-case matching

This benchmark matches the last route and unknown route. It generates a randomly prefixed and suffixed route in an attempt to thwart any optimization. 1,000 routes each with 9 arguments.

This benchmark consists of 6 tests. Each test is executed 1,000 times, the results pruned, and then averaged. Values that fall outside of 3 standard deviations of the mean are discarded.

Test Name	Results	Time	+ Interval	Change
r3 - unknown route (1000 routes)	993	0.0000064563	+0.0000000000	baseline
r3 - last route (1000 routes)	999	0.0000089408	+0.0000024845	38% slower
FastRoute - unknown route (1000 routes)	963	0.0005773683	+0.0005709121	8843% slower
FastRoute - last route (1000 routes)	999	0.0006089654	+0.0006025091	9332% slower
Aura v2 - last route (1000 routes)	999	0.2159689919	+0.2159625356	3344993% slower
Aura v2 - unknown route (1000 routes)	985	0.2432910672	+0.2432846109	3768179% slower
