Add `ibis` as a new backend

[ianwhale]

Missing functionality

I would love to be able to profile a table in a database without sampling down to pandas.

Proposed feature

Add ibis as a new backend.

As shown in their docs, this would open up profiling on a ton of platforms (ClickHouse, DuckDB, Flink, MySQL, Snowflake, etc.).

I have a work in progress here. Its not demo-able yet but the tests are passing!

Would the team be open to such a contribution?

Alternatives considered

One could just use sqlglot to limit dependencies. However, this would lose the DataFrame interface already followed by the pandas and spark backends.

Additional context

I see this issue from a while ago: #1552.

The suggestion I'm making is quite different. As I say above it would look like an additional backend like the spark functionality.

Update on this: I have something demo-able on the branch linked above.

Reproduction steps:

uv venv --python 3.9
source .venv/bin/activate
uv pip install ibis-framework[duckdb,examples] \
    git+https://github.com/ianwhale/ydata-profiling.git@feat/ibis-backend[ibis] \
    setuptools
python script.py

Where script.py is:

import ibis
from ydata_profiling import ProfileReport
from ydata_profiling.config import IbisSettings

ProfileReport(ibis.examples.penguins.fetch(), config=IbisSettings()).to_file("report.html")
