[DOCS] Tutorial: FOTW data access

[avriiil]

This adds the first FOTW tutorial on Data Access.

I haven't been able to figure out yet how to render the .ipynb as HTML. I've toyed around with index.rst in the new tutorials directory and the toctree but I must be doing something wrong. How does this work?

We should also decide where we want to store the toy data:

• in the docs (probably not?)
• just on Github and point folks there if they want to run the code
• everything on S3 (not ideal because we want to show off local reads too)

TO DO
[x] decide where to store toy data
[x] render notebook as html
[x] store some simple delta data in daft-public-data bucket

For (1):

• all the toy data is here: https://github.com/avriiil/daft-examples/tree/main/data

For (3):

• delta table could be as simple as:

df = daft.from_pydict({
    "A": [1, 2, 3, 4],
    "B": [1.5, 2.5, 3.5, 4.5],
    "C": [True, True, False, False],
    "D": [None, None, None, None],
})

df.write_deltalake(...)

@jaychia -- this should be good to go now, lmk what you think!

This is looking pretty good @avriiil!

Were you able to figure out the rendering issues? I also left some comments about the files in to-remove which I'm assuming we just forgot to-remove? 😛

[jaychia]

Why is this under to-remove? Are they still used?

[avriiil]

Good catch @jaychia -- redundant files have been removed. Notebook renders well now:
