add writing positions of tray and pot to timestream
Update for new YAML setting file. Things to consider:
- The output root folder now should contains corrected images and segmented images. So the name should not contain "orig" or "corr" or "segm"
- The output streams should be "corr" and "segm" and the folder of these stream should contain the base folder as the affix. An example is "/mnt/phenocam/a_data/TimeStreams/Borevitz/BVZ0018/BVZ0018-GC05L-C01~fullres"
- The CVS file should be in "*-segm/_data/" folder
- The timestream should allow to update timestream.image_data for existing images.
