dinglehopper --version, ocrd-dinglehopper --version

[mikegerber]

Apparently there is no --version parameter and it would be good to have one - now that we have versions.

• [x] Add --version
• [x] ocrd-dinglehopper --version is broken now? (reports None)

This came up because I have a user who reported a problem and it would be great if I could narrow down what version he's using.

This is a bug:

❯ ocrd-dinglehopper --version
Version None, ocrd/core 2.58.1

(should not report None)

The non-OCR-D CLI now has --version:

❯ dinglehopper --version
dinglehopper, version 0.9.7

OCR-D CLI is now fixed:

❯ ocrd-dinglehopper --version
Version 0.9.7, ocrd/core 2.67.0
