[Feat] Camera Storage info

[Romakita]

As a developer I want a method to get all storage info available on a Camera.

Example GPPhoto2

gphoto2 --storage-info
[Storage 0]
label=NIKON D70
basedir=/store_00010001
access=2 Read-only with delete
type=4 Removable RAM
fstype=4 Camera layout (DCIM)
totalcapacity=7822432 KB
free=7452704 KB
freeimages=697

StorageInfo interface

{
  "label": "NIKON D70",
  "basedir": "/store_00010001",
  "access": "2 Read-only with delete",
  "type": "4 Removable RAM",
  "fstype": "4 Camera layout (DCIM)",
  "totalcapacity": "7822432 KB",
  "free": "7452704 KB",
   "freeimages": 697
}

Acceptance criteria

• Add method Camera.storageInfo(): StorageInfo[]
• Return an array of StorageInfo

@Nic2012
here the feature. Can you check, if the description is right ?

I think so, thats fine.
Well in my earlier apps I grep the stdout from gphoto2-cli, transformed it by jq to get finally

  "storage-info": [
    {
      "label": "NIKON D70",
      "basedir": "/store_00010001",
      "access": "Read-only with delete",
      "type": "Removable RAM",
      "fstype": "Camera layout (DCIM)",
      "totalcapacity": "7822432",
      "free": "7516544",
      "freeimages": "703"
    }
  ],

There is an annoying mixture between type number and description in some fields e.g.
"4 Removable RAM", but we developer can suppress it later when we fetch data.
