feat(storage): allow #a=1&b=2 params; HTTP can use #fname=XXX

HTTPStorage:
  Consider https://civitai.com/api/download/models/15603
  Which has a content-disposition of "Light and Shadow.safetensors"
  But we don't know that in advance, so we'd have to perform the
  request each time to see if the file is already cached locally.
  To avoid that, we can now give a URL like
    http://.../models/15603#fname=light-and-shadow.safetensors
  Which will check the cache against this filename.

Notes:
  * Hash query is never sent to to the server.
  * Application code might still manipulate the filename, e.g. in
    the above case, the final name might be
      `lora_weights--light_and_shadow.safetensors`
    in the diffusers cache directory.
