30eea3915b resources: Regenerate image golden testdata
Keep this as a separate commit as this isn't because the files have changed. The filenames have changed due to cache busting of PNG and Webp images.

ba1d0051b4 media: Make Type comparable
So we can use it and output.Format as map key etc.

This commit also fixes the media.Type implementation so it does not need to mutate itself to handle different suffixes for the same MIME type, e.g. jpg vs. jpeg.

This means that there are no Suffix or FullSuffix on media.Type anymore.

0a2ab3f8fe exif: Allow more spacing characters in strings
The root cause of issue #8079 was a non-breaking space (U+0160).
`unicode.IsPrint` only allows the ASCII space (U+0020).  Be more lenient
by using `unicode.IsGraphic` instead.

3ba147e702 images: Add images.Overlay filter
This allows for constructs ala:

```
{{ $overlay := $img.Filter (images.Overlay $logo 50 50 )}}
```
Or:

```
{{ $logoFilter := (images.Overlay $logo 50 50 ) }}
{{ $overlay := $img | images.Filter $logoFilter }}
```

Which will overlay the logo in the top left corner (x=50, y=50) of `$img`.

158e7ec204 Fix incorrect MIME type from image/jpg to image/jpeg
According to multiple sources, both official ([IANA] and [RFC2046]) and
otherwise (eg, [Mozilla] and [Wikipedia]), the official MIME type for
JPEG images is `image/jpeg`, not `image/jpg`.  Change Hugo to match.

[IANA]: https://www.iana.org/assignments/media-types/media-types.xhtml#image
[RFC2046]: https://tools.ietf.org/html/rfc2046

e5856e61d8 resources: Support output image format in image operations
The image format is defined as the image extension of the known formats,
excluding the dot.
All of 'img.Resize "600x jpeg"', 'img.Resize "600x jpg"',
and 'img.Resize "600x png"' are valid format definitions.
If the target format is defined in the operation definition string,
then the converted image will be stored in this format. Permalinks and
media type are updated correspondingly.
Unknown image extensions in the operation definition have not effect.

Add image.Exif
Note that we will probably need to add some metadata cache for this to scale.

Add a set of image filters
With this you can do variants of this:

```
{{ $img := resources.Get "images/misc/3-jenny.jpg" }}
{{ $img := $img.Resize "300x" }}
{{ $g1 := $img.Filter images.Grayscale }}
{{ $g2 := $img | images.Filter (images.Saturate 30) (images.GaussianBlur 3) }}
```

Image resource refactor
This commit pulls most of the image related logic into its own package, to make it easier to reason about and extend.

This is also a rewrite of the transformation logic used in Hugo Pipes, mostly to allow constructs like the one below:

    {{ ($myimg | fingerprint ).Width }}
