4.25.0: Basic support for Canon maker notes, custom build fixes

There is now support for getting the AutoRotate value from Canon photos. The main value from this is when Orientation does not reflect the correct orientation of a contained thumbnail (Canon cameras seem to, in some situations, rotate the image, reset the Orientation tag, but then leave the thumbnail as it was).

However, this is also groundwork to be able to get more tags from Canon's own maker note tags, if there is interest in it.

This release also includes a couple of custom build fixes which will make the build smaller in some circumstances (mainly when using PNG and excluding exif and iptc).

4.24.0: Simpler thumbnail enabling in custom builds

When making a custom build and including thumbnail, and at the same time including specific Exif tags, you would have to make sure to include the tags JPEGInterchangeFormat and JPEGInterchangeFormatLength for the thumbnail to be present in the result.

Now this is handled automatically. Either set "exif": true or any array.

There was a bug that caused a custom build to not do anything on Windows.
