Problem with some CRS transformations

[glaroc]

We have a problem with some collections in our STAC catalog that are in less common reference systems.

For example, this collection has one item in epsg:3347, and a simple stack() produces an error, even when not changing the CRS from the input source.

import pystac_client
import stackstac

catalog = pystac_client.Client.open("https://io.biodiversite-quebec.ca/stac")

items = catalog.search(
    collections=["pither_functional_connectivity"]
).item_collection()
stack = stackstac.stack(items, resolution=300, epsg=3347, bounds=(7227806, 1242748, 7602593, 1529390))

Here is the error

Traceback (most recent call last):

pyproj.exceptions.ProjError: transform error: Invalid coordinate: (Internal Proj Error: lcc: Invalid latitude)

Any help or guidance as to why this could be happening would be appreciated. We don't have this problem with other collections. Happens with stackstac==0.5.1 and pyproj==3.6.1.

This is probably an issue with the bbox in our STAC catalog being in the CRS of the item, and not in 4326. Will revisit once corrected.
