[BUG] Cannot add second assay to my ARC

[HLWeil]

OS and framework information (please complete the following information):

• OS: Windows 11
• ARCitect version 0.0.46

Describe the bug

• In the ARC: https://git.nfdi4plants.org/weil/SugarExample
• Zero registration
• I'm trying to add a second assay to an ARC, and nothing happens, FileSystem is also unchanged

• The first Assay in the ARC contains a DataMap which works just fine
• Adding a second study is possible

[HLWeil]

It's related to Datamap, reproducible steps:

1. Create new ARC
2. Add Assay
3. Add Datamap to Assay
4. Add 1 Row to Datamap and fill out any cell
5. Try to add second assay
6. Nothing happens

Is this then not an ARControl issue?

[HLWeil]

Yesn't. The issue is, ARCtrl writes the datamap as its own isa.datamap.xlsx per default. This is fine by specification and was the initial default.
Now the problem is, that by specification, it is also fine to write the datamap as a sheet directly in the assay file. Swate goes this route, making everything function fine when having a single assay, which is written by Swate also in ARCitect.
When you add a second assay, ARCitect apparently also get's handed the Datamap write contract from ARCtrl. This it can't fulfill because the implementation is missing.

My route now: related to nfdi4plants/ARCtrl#407, I'll add at a toggle between writing the file or the sheet. ARCitect can then just choose to always write the sheet.

Fixed in #285
