Refactor Dataflow View

Closes #70

There's a bit of overlap between your 3 PRs.

First, there's some confusion about what belongs to refactor-default (#99) and fix-physical-components (#100):

* cbc038b (origin/refactor-default) refactor: Shorter collector function
| * 90099cc (origin/fix-physical-components) feat: Add Physical Links for Context Diagrams
| * 7972e0b test: Add test case
| *   8a1111b merge: Merge better code PR
| |\
| |/
|/|
* | ee52fd4 refactor: Code improvements
| * 01ca54b test: Add test data
|/
* 8634a24 (tag: v0.2.36) Add-owners (#98)

Then there's also ee52fd4 - in both #99 and #100, see above - and 1936ce9 - in here -, which are both described as "refactor: Code improvements", but are vastly different from each other:

The second part is probably gonna be fine if things just get squashed together as usual, but the first part might be worth addressing regardless, just to decouple the two PRs (if that even makes sense).
