Allow Denormalising Keys for Azure Storage

[amandesai01]

Environment

• Node.js: v24.6.0
• npm: 11.5.1
• Yarn: 1.22.22
• Nuxt: ^3.17.4

Reproduction

call setItem or setItemRaw for a specific path after mounting Azure blob storage driver.

Describe the bug

I am using Azure blob driver, and I am unable to upload nested blobs. Upon inspection, we found that while normalising keys, / is replaced with :. This stops application from posting files into nested folder.

Proposed Solution (Which we are currently doing):
Allow an options flag into Azure driver, called allowNestedPath (or something similar). Then, inside all the getters and setters, replace / back instead of :.

Open to fixing this if approved.

A better (and more future proof) way to do this is to allow drivers to expose prefs back to unstorage (to customise behaviour), and that could contain a flag to stop unstorage from normalising keys.
