AzureML fsspec Protocol Handler

The `azureml-fsspec` library enables the `fsspec` (Filesystem Spec) library to interact with Azure Machine Learning datastores. It registers 'azureml://' and 'adl://' protocols, allowing users to access, read, and write files within Azure ML datastores using the familiar `fsspec` API. The current version is 1.3.1, and it's released as part of the broader Azure ML SDK ecosystem, typically following its release cadence.
