feat: `get_obstore_store` function for creating Obstore store with Open PC credentials

[kylebarron]

Obstore is an alternative to fsspec that's cleaner and can be more performant.

We might also want to consider whether there's an API that would allow to construct a store with either open PC or PC pro with a single function signature?

Can you please remove Python 3.8 from the test matrix?

[kylebarron]

Obstore doesn't have wheels for 3.8 so this CI is failing on version 3.8. So we should remove the CI tests for 3.8 as well.

[kylebarron]

I removed Python 3.8 from CI @ghidalgo3

Note that the minimum Python version for install is still 3.7: https://github.com/microsoft/planetary-computer-sdk-for-python/blob/4df68b5b720541690ad7b63c3183dc530161d8e3/pyproject.toml#L9

[ghidalgo3]

Can you please also increase the minimum python version in the toml to 3.9?

[ghidalgo3]

I have edited the settings to allow your commits to run CI/CD automatically.

[kylebarron]

I'm not sure it worked

[kylebarron]

@ghidalgo3 looks like CI is finally passing!
