Added general PPMS plugin

[JonathanNoky]

Added the PPMS plugin. Up to now, it can deal with ETO and ACT measurements. More types like magnetization measurement will follow soon.

hi @JonathanNoky

few points:

• you find now def set_entrydata_definition(self): around in the code. Here is where you can add any kind of class that must be used by the parser. In this way, you can inherit and specialize this parser into your plugin, you can change the classes used, and also extend the set of variable defined to include new classes
• if you use the virtualenvironment where nomad is installed you get also the ruff linting tools (ruff check . --fix and `ruff format .) so you get linted code
• more comments in specific lines of the MR
• insert test data in the folder tests/data/ppms so we can test the plugin

Hey @ka-sarthak, any hint why this is failing?

https://github.com/FAIRmat-NFDI/nomad-measurements/actions/runs/12356184054/job/34481491564?pr=133

it says it doesn't find mongoengine

[ka-sarthak]

It seems to be coming when using nomad.search in the ppms parser. This is strange, as we have always used nomad.search, however in the normalize and not the parser, without having to install mongoengine

@JonathanNoky tell me if some point is not clear

[aalbino2]

If you see in this branch, I moved the test file for XRD in a dedicated folder. I will need to change the paths in the test.

IS it okay for you to organize the test files in subfolders @ka-sarthak ?

[ka-sarthak]

@aalbino2 Sure, tests/data/xrd looks good

[aalbino2]

The sequence file leads to a failure.

Probably the way we pass the class to be instantiated must be modified:

The other .dat file is not matched.

I will merge this PR and open new issues for further development @JonathanNoky
