[refactor] driver hamamatsurx: simplify return type for *ParamsList

[pieleric]

Don't return the length of the list, as first argument, but just warn if it's not the
actual length.

There were only 3 callers using the functions, and all had the wrong
expectation.

Pull request overview

Refactors the Hamamatsu RemoteEx driver (hamamatsurx.py) so the various *ParamsList() helpers return only the parameter-name list (dropping the leading “reported count”), while still warning when the reported count doesn’t match the received number of parameters.

Changes:

• Updated MainParamsList/GenParamsList/AcqParamsList/CamParamsList/DevParamsList/SeqParamsList to strip the leading count and log warnings on unexpected/empty/mismatched responses.
• Added/adjusted return type hints to consistently represent RemoteEx responses as List[str].
• Improved docstrings to reflect the simplified return contract for *ParamsList().

📝 Walkthrough

Walkthrough

This PR adds comprehensive typing annotations to the StreakCamera class in hamamatsurx.py and standardizes how six parameter list methods (MainParamsList, GenParamsList, AcqParamsList, CamParamsList, DevParamsList, SeqParamsList) parse RemoteEx command responses. A new internal helper _send_params_list_cmd consolidates response parsing logic: methods now return List[str] containing only parameter names, validate the embedded parameter count against the actual list length, emit warnings on mismatches, and return empty lists for null responses. The base sendCommand method gains a List[str] return type, and related parameter query methods (AcqParamInfoEx, CamParamGet) receive explicit input and return type hints.

1678-1686: ⚡ Quick win

Shared error handling pattern may return malformed data across all *ParamsList methods.

All six *ParamsList methods (MainParamsList, GenParamsList, AcqParamsList, CamParamsList, DevParamsList, SeqParamsList) share the same error handling pattern: when parsing result[0] as an integer fails, they return the raw result list. This could include an unparseable count as the first element, which violates the documented return type of "list of parameter names."

Callers expect only parameter names (e.g., if "TimingMode" in avail_params at line 149). Returning malformed data could cause subtle bugs if the first element is not a parameter name.

Recommendation: Consider returning [] instead of result when parsing fails, or add comments explaining that returning result is intentional defensive programming for devices that might return parameters without a count prefix. The logged warning helps debugging, but an empty list return would be more robust against truly malformed responses.
