Settings - metadata - add high level rw options

[user0]

XnViewMP 1.7.1 64bit
Windows11 (23H2), display resolution 3840x2160, win scaling 150%

Settings - metadata
managing metadata is not clear enough

Note1: Edit XMP/IPTC dialogs' functionality do not depend on Settings>Metadata and not reviewed here.
Note2: splitting Companion files/Sidecars settings into 2 tabs is a bit odd, since Sidecars is a subset of Companion files. However, I'm not sure if/how they should be combined yet.


Suggestion - WIP

• add high level read/write options for metadata
  on high level - what to do
  on low level (at individual tabs) - how to do
  
  • existing Metadata tab
    - rename tab → IPTS & XMP
  • Sidecar tab
    - move 'Update or create XMP Sidecar' to new tab

• add Read order
  since there are multiple sources to read, explicit order could be useful
  - maybe add some message that there are some conflict data between different sources

Example

• Adobe Bridge, CameraRAW, Lightroom

• digiKam, CaptureOne

Good! About "Read order", I think that "Mockup A" is better.
