optimize batch generation of previews
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

allow keeping multiple preview "versions" of the same 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

Add new Provider interface for preview providers
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

Only generate previews in powers of 4 and set min
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.

Check if a preview provider is available before using it
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.

Max preview size to 4096x4096
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

Only return 1 type
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.

Don't lie about the preview mimetype
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.

Don't generate max preview twice
If you request a preview of X by Y. And after calculating X and Y are
equal to maxWidth and maxHeight then there is no reason to create a
preview of that size.
