user_usage_report keeps a counter for files read.
The app uses
- OC_Filesystem::read hook
- Event listener (the legacy one) for IPreview::EVENT
Request for previews do not trigger the hook, hence the additional event listener.
The thumbnails for a list or grid view should not count, so we need the width and height.

getCachedPreview used to call `getFile`, and this calls `getDirectoryListing` (or underlying function that list directory) to find the file. This was done for every preview spec.
Now, this is done only once at the beginning of the loop, and the array is just iterated when needed to find the correct entry.

If the maximum preview generated gives some kind of invalid IImage, it's dimentions and filename can be set to zero.
And then later we do a division by zero to keep the aspect ratio of the previews.

Make sure that when fetching the image from the cache we don't
accidentally fetch the cropped image just because it also start with
256-256

The $crop parameter was not propagated to the imaginary pipeline and
instead it used the smartcrop algorithm always

Currently if the following situation happens
Server generates preview
Server has command removed which allows a preview to be shown
Client asks for preview, gets a 404 error when preview exists
(Mime checked before preview)
This happens more often with documents, or video as the commands are not
native PHP, they require a binary on the server.
After the fix the following would happen
Server generates preview
Server has command removed which allows a preview to be shown
Client asks for preview, gets preview which has been generated
(Mime checked after preview)
This would also allow offline generation (for example a docker image
containing the extra binaries), allowing a reduction in attack surface
of the instance serving the preview data.

by allowing the generation of multiple previews at once we save on having to find, open and decode the max-preview for every preview of the same file
the main use case for this is the preview generator app (pr for that comming next)
in my local testing this saves about 25% of time when using the preview generator app

* Order the imports
* No leading slash on imports
* Empty line before namespace
* One line per import
* Empty after imports
* Emmpty line at bottom of file

The main use case here is storage provided versioning where we dont have
separate file ids for all the versions, by allowing a prefix for the
version we can store separate previews for all the versions.
Additionally, by keeping all the version previews in the same folder as the
"normal" previews they will be cleaned up properly when the file is deleted

the main difference is passing the `File` object to the provider
instead of a `View` + path
Old providers will still continue to work as before

Before we'd round up all preview request to their nearest power of two.
This resulted still in a lot of possible images. Generating a lot of
server load and taking up a lot of space.
This moves it to previews to be powers of 4: 64, 256, 1024 and 4096
Also the first two powers are always skipped (4, 16) as it doesn't make
sense to generate previews for that.
We cache preview pretty agressively and I feel this is a better
tradeoff.

Else if a preview provider is registerd but not available (for example
missing support in some external lib). It will do 💥. This way the
providers can at least do the sanity checks required.
