Add a benchmark for compiling large fluent files

[leamingrad]

This PR adds a new benchmark to the project for compiling a fluent file with 10K items it.

While the benchmark itself relies on a static file, I've included the script that I used to generate it.

Sample results

The test fails due to an issue on master I have resolved, this is good to go. Thanks!
