Pass version as a command line argument to benchmark script

[lupomontero]

It could be a good idea to pass the version we want to compare to as a command line argument. That way, by default it would compare the local source code vs the latest published version.

npm run benchmark

Alternatively, you would also be able to compare to a specific published version (ie: v1.13.0):

npm run benchmark -- v1.13.0

To achieve this I think we'd only need to change the following line:

psl/benchmark/suite.js

Line 113 in 440248a

const compareToVersion = 'v1.13.0';

Into this:

const compareToVersion = process.argv[2] || 'latest';

CAVEATS:

• The benchmarking script only works on ESM (it uses vm.SourceTextModule), so we can only compare to 1.13.0 and above.
• If a string that is not a valid published version is passed in, the script simply fails ungracefully.
