fix: xmp jpeg write

[cdmurph32]

Changes in this pull request

Adding the manifest url to large XMP segments could cause the XMP data
to exceed the limit of 65503 bytes.

There were 3 causes of this issue:

1. Extra whitespace from formatting. The quick_xml writer shiftwidth
   could be much larger than that of the original. Potentially adding
   several KB of whitespace.
2. Manifest url added multiple times. The manifest url was added to
   multiple keys within the XMP data.
3. Lack of padding awareness. According to the spec, XMP segments should
   have 2KB to 4KB of padding. The padding should be adjusted to keep
   the XMP data length the same with the addition of the remote manifest
   url. This is important for data hashes as it keeps the offsets of the
   JPEG metadata the same.
