Tokio hangs when opening TIFF

[maxrjones]

This example seems to hang, @kylebarron suggested in may relate to the intersection between exceptions, panics, and async futures

from async_tiff import TIFF
from async_tiff.store import HTTPStore
from urllib.parse import urlparse
import asyncio

year = 2000
file_name = "50N_120W"
url = f"https://storage.googleapis.com/earthenginepartners-hansen/GLCLU2000-2020/v2/{year}/{file_name}.tif"
parsed = urlparse(url)
store = HTTPStore.from_url(f"{parsed.scheme}://{parsed.netloc}")
async def open_tiff(*, store, path):
    return await TIFF.open(path, store=store)

tiff = asyncio.run(open_tiff(store=store, path=parsed.path))
print(tiff)

fyi @TomNicholas

FWIW I saw this issue apache/arrow-rs-object-store#343 which linked to this upstream issue rust-lang/rust#136932. When I was debugging this issue, I remember seeing a panic somewhere with u16::Display. I was super confused at the time, but I'm curious if maybe this was a regression with rustc? Maybe we should test with another rust version

Tested on rust 1.86 and 1.87, getting the same hang behaviour on both so don't think it's related to those issues. I can reproduce this purely on the rust side too (when working on #101 (comment)), so at least we can deduce that it's not something with pyo3.

Yeah... I'm kinda stumped about this hanging 😔
