Add style benchmark

[msbarry]

Add a benchmark that evaluates each transportation style layer filter expression on each transportation feature in a few tiles.

On my machine I'm seeing:

❯ node scripts/benchmark.js     
(node:84076) ExperimentalWarning: The Fetch API is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
122.5ms evaluate expressions nyc z12 x 8.16 ops/sec ±0.25% (25 runs sampled)
108.0ms evaluate expressions boston z12 x 9.26 ops/sec ±0.11% (28 runs sampled)
0.1506ms evaluate expressions kansas z14 x 6,642 ops/sec ±0.22% (101 runs sampled)

Awesome! Workflows are currently in a broken state pending #879 but once that's resolved, we can incorporate this into the ongoing work (#881) to automatically generate PR statistics.
