FIX: Windows failing build and querying

[parmesant]

Fixes #824 and Failing builds on windows

Description

For #824, the file path being passed to PartitionedFile struct is being modified if the storage_mode is drive (for s3-store, and blob-store the current code works just fine)

For failing windows builds, a cfg!() is added to tokio::select! macro to handle different signals for different underlying OS
