chore: rudimentary Python benchmarks & support more Polars types
I had to patch a hole in Polars type conversion as well.
I do not understand why duckdb is so slow. Maybe Arrow conversion is very expensive?
Ideally there should be no gap between `test_scan_XXX` and each engine's XXX benchmark because
all of these queries are simple O(N) scans.

### Release Notes
<details>
<summary>tokio-rs/tracing (tracing-subscriber)</summary>
###
[`v0.3.20`](https://redirect.github.com/tokio-rs/tracing/releases/tag/tracing-subscriber-0.3.20):
tracing-subscriber 0.3.20
[Compare
Source](https://redirect.github.com/tokio-rs/tracing/compare/tracing-subscriber-0.3.19...tracing-subscriber-0.3.20)
**Security Fix**: ANSI Escape Sequence Injection (CVE-TBD)
#### Impact
Previous versions of tracing-subscriber were vulnerable to ANSI escape
sequence injection attacks. Untrusted user input containing ANSI escape
sequences could be injected into terminal output when logged,
potentially allowing attackers to:
- Manipulate terminal title bars
- Clear screens or modify terminal display
- Potentially mislead users through terminal manipulation
In isolation, impact is minimal, however security issues have been found
in terminal emulators that enabled an attacker to use ANSI escape
sequences via logs to exploit vulnerabilities in the terminal emulator.
#### Solution
Version 0.3.20 fixes this vulnerability by escaping ANSI control
characters in when writing events to destinations that may be printed to
the terminal.
#### Affected Versions
All versions of tracing-subscriber prior to 0.3.20 are affected by this
vulnerability.
#### Recommendations
Immediate Action Required: We recommend upgrading to tracing-subscriber
0.3.20 immediately, especially if your application:
- Logs user-provided input (form data, HTTP headers, query parameters,
etc.)
- Runs in environments where terminal output is displayed to users
#### Migration
This is a patch release with no breaking API changes. Simply update your
Cargo.toml:
```toml
[dependencies]
tracing-subscriber = "0.3.20"
```
#### Acknowledgments
We would like to thank [zefr0x](http://github.com/zefr0x) who
responsibly reported the issue at `security@tokio.rs`.

project, please email us at `security@tokio.rs`.
