Moved from benthemonkey#1

I spotted the article Maybe you don't need Rust and WASM to speed up your JS written by @mraleph and decided to try to port non-hardcore optimizations.

I benchmarked it with node 14.15.4.

Before:

Parsing source map
iteration: 3.590s
iteration: 3.306s
iteration: 3.459s
iteration: 3.546s
iteration: 3.379s
iteration: 3.562s
iteration: 3.319s
[Stats samples: 7, total: 24158 ms, mean: 3451.1428571428573 ms, stddev: 128.1444497432487 ms]

After:

Parsing source map
iteration: 1.030s
iteration: 1.769s
iteration: 1.104s
iteration: 1.118s
iteration: 1.189s
