Release Name: "I think rain that is wet", thought Zaphod Beeblebrox, " so who am I to judge?" (4.1.0)

Notes:
Most notable changes for this release:
- GUI upgraded from Qt5 to Qt6 -- now supporting the new Apple silicon
- A new `<<>>` dynamic run-index (default), that behaves the same as `<<1>>` when multiple runs are acquired, otherwise it is omitted/void (PR #195)
- Manpages (not on Windows)
