feat(filesystem): implement a csv reader with duckdb engine

[IlyaFaer]

Towards #299

A raw version of the source to discuss some details.

Test data in a form of CSV files and folders is required in different buckets. For now, I tested it on my local filesystem:

Data from two CSV files is read and saved in the same table. As it works through the filesystem source, all the kinds of storages supported by filesystem are supposed to be working here as well. But as I don't have straight access to the buckets to create test CSV files, I had to use local file system.

@IlyaFaer good start. check my comment in read_csv

This PR requires another PR to be merged first: dlt-hub/dlt#906

it's so cool that passing fsspec file works with duck db! next steps:

• move it to filesystem source, see review
• you still do not read in batches really (see review)
• I think we need both json and arrow option when yielding items (see review :)

OK this is not a WIP anymore - we are almost ready to merge :)

1. pls fix the review
2. pls add demo (can be super simple along stream_and_merge_csv)
3. pls document new reader in filesystem README

@IlyaFaer could you also look at this: https://clickhouse.com/docs/en/getting-started/example-datasets/nyc-taxi it is a taxi dataset as zip csv. it is quite large. pls make sure you can ingest it with duckdb reader

1. make sure we ingest zip streams (I think duckdb detects compression)
2. you do not need to load it all
3. you may add this as a duckb example I asked above

LGTM!

files are added, but the core PR must be fixed and merged first
