Benchmark result of docs/scripts/readme_plot.py, native expression vs concise/simple API

[rht]

For both pandas and Polars, there are at least 3 ways to do things for each steps. But they can be roughly split into 2: using native expression and using a simpler, more concise API. We should split further into 4 agents:

1. MoneyAgentPolarsNative
2. MoneyAgentPolarsConcise
3. MoneyAgentPandasNative
4. MoneyAgentPandasConcise

and benchmark them. Because:

1. researchers who want to speed up their code further could see if the effort is worth it
2. it could become a how-to guide on speeding up the code further via the native expression

I got this error

This is a good idea, we can also check the performance overhead of mesa-frames.
I corrected the bug in main, i will make the necessary changes in #23.

Closed via #23 and #24.
