Hi,

I've fixed merge conflicts and sort package approximately alphabetically
apply python-pynetdicom and Maxim's suggestions in separate commits.

- python-pydicom was added already
  - issue :: https://issues.guix.gnu.org/55989
  - commit :: e24b9b42bc9a78bc63e6824e74fc6850e8a90490

The patch adding python-pynetdicom pushed as
e71abbc6438f2b25f0d41221fadf695dfe094689 to master.

Thanks,
Oleg
