Detect archive type of extension to decompress

[kylecarbs]

We've filled the client zip implementation with tar so we can eventually load extensions on the client. Installing from a VSIX no longer works because the standard format is a zip.

We should detect the archive type then use the appropriate fill.

Not sure what the limitations are here but is using the CLI an option?

I was able to mess around and figure out their public API for the extension gallery.

curl -X POST \
  'https://marketplace.visualstudio.com/_apis/public/gallery/extensionquery?api-version=5.1-preview.1' \
  -H 'Content-Type: application/json' \
  -H 'api-version: 5.1-preview.1' \
  -H 'cache-control: no-cache' \
  -d '{
    "assetTypes": [
        "Microsoft.VisualStudio.Services.Icons.Default",
        "Microsoft.VisualStudio.Services.Icons.Branding",
        "Microsoft.VisualStudio.Services.Icons.Small"
    ],
    "filters": [
        {
            "criteria": [
                {
                    "filterType": 8,
                    "value": "Microsoft.VisualStudio.Code"
                },
                {
                    "filterType": 10,
                    "value": "php"
                },
                {
                    "filterType": 12,
                    "value": "37888"
                }
            ],
            "direction": 2,
            "pageSize": 54,
            "pageNumber": 1,
            "sortBy": 0,
            "sortOrder": 0,
            "pagingToken": null
        }
    ],
    "flags": 870
}'

Howdy @RiFi2k, this isn't related to the current issue, but thank you for the suggestion. The reason we're not using the official VS Code Marketplace is because it is a restriction in their TOS. See the following comment from one of our CTO's: #30 (comment).
