  1. [POC]: Added "pc" fsspec filesystem 

    This adds a "pc" fsspec filesystem implementation, which lets us
insert "pc::" in an fsspec URL and automatically sign it when loading
it with an fsspec client.

The primary motivation is integration with fsspec's filesystem where
users would need to call `planetary_computer.sign` in multiple places

1. Once for loading the index JSON files
2. Once for signing the reference filesystem templates

Which lets us replace this:

```python
>>> result = xr.open_dataset(
...     fsspec.get_mapper(
...         "reference://",
...         fo=planetary_computer.sign(requests.get(planetary_computer.sign("https://deltaresreservoirssa.blob.core.windows.net/references/reservoirs/chirps.json")).json()),
...     ),
...     engine="zarr",
...     consolidated=False,
... )
```

With this:

```python
>>> result = xr.open_dataset(
...     "pc::reference::pc::https://deltaresreservoirssa.blob.core.windows.net/references/reservoirs/CHIRPS.json",
...     engine="zarr",
...     consolidated=False,
... )
```
