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.

To allow us to create previews of files stored in appdata we need to
construct the view differently.

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.

Exporting all pages of a document to a PDF is a waste of time. All we
need is a thumbnail of the first page anyway. Plus, reading that PDF
(even just the first page of it) into imagick is presumably much
slower than reading a simple PNG.

When a version of a file is restored the previews are no longer valid.
Thus we should remove them so they are regenerated.

This code had the potential to time out. If a huge folder with pictures
for example was deleted then this could easily grow the number of files
to clean with a factor 5 (or more).
Now the previews just get cleaned up in the background. Which is good
enough for the 99% case
As a bonus this now also keeps the previews when in the trashbin so you
don't have a spiking server load when a user opens the trashbin view.

With HiDPI screens. And even normal HD screens you want more detail from
your pictures. Or the ability to somewhat zoom on you previews. For this
we need somewhat larger previews.
Moving the default to 4096x4096 is a step up. Users that want the old
behavior can still set the values in config.php

Throw proper exception if we can't get the mimetype for a preview. Catch
it later on so we can just return a not found for the preview.

For legacy reasons we stored all the previews with a png extention.
However we did not put png data in them all the time.
This caused the preview endpoints to always report that a preview is a
png file. Which was a lie.
Since we abstract away from the storage etc in the previewmanager. There
is no need anymore to store them as .png files and instead we can use
the actual file extention.
