plotAPI prefs source_url with local quadfeather tiles dir

[rhodesch]

I've followed the Quick Start section and it rendered plots when I specified a web hosted quadfeather directory. The page is blank when I specify a local directory. Any help would be appreciated.

python3 -V
Python 3.10.0

git clone https://github.com/nomic-ai/deepscatter
cd deepscatter
quadfeather-test-data 1_000_000
quadfeather --files tmp.csv --tile_size 50_000 --destination tiles

update index-simplest-way-to-start.html, L15

import { Scatterplot } from './src/deepscatter';

Looking at /tiles contents more closely the feather files seem valid:

>>> import pyarrow.feather as feather
>>> feather.read_feather("tiles/0/0/0.feather")
