Consider if and what we want to improve for parsets
We copied the issue RAP-32 for our Jira board.
Description
We might want to improve Dp3s parset. For example, the "msout" is rather unlogical; if no output step is given, it will write; if a dummy or split step is given it is not. Also, the `msout=.` and `msout=` are confusing, and it might be better to use a separate keyword for that functionality (msout.force_write).
We could consider defining a style for our keywords; e.g. to always use lower snakecasing and avoid small abbreviations.
We could also quickly consider whether the current text file is still the most desirable one. using JSON could also be an option.
Acceptance criteria:
- A plan is made and described (in the comments of this ticket or elsewhere)
- New tickets are defined to do the work.
