Character %2F is automatically converted to / in URL param

[severo]

When passing a parquet URL that contains the character %2F, it seems that the character is considered as /, which convert the original URL to a different one.

See, for example, the file: https://huggingface.co/datasets/squad/resolve/refs%2Fconvert%2Fparquet/plain_text/squad-train.parquet.

The app gives the following error:

Error

in these two cases:

• original: https://lite.datasette.io/?parquet=https://huggingface.co/datasets/squad/resolve/refs%2Fconvert%2Fparquet/plain_text/squad-train.parquet
• replacing %2F with '/' (does not exist): https://lite.datasette.io/?parquet=https://huggingface.co/datasets/squad/resolve/refs/convert/parquet/plain_text/squad-train.parquet

Note, in case somebody looks at this issue to load a HuggingFace dataset with lite.datasette.io, we now provide a simpler API to access the parquet files:

https://lite.datasette.io/?parquet=https://huggingface.co/api/datasets/glue/parquet/ax/test/0.parquet

It does not contain %2F this time 😄
