Regression: cannot run in batch mode

[orionlee]

With the current code in master, running LATTE in batch mode almost always silently failed.

E.g. with the following input csv,

TICID,sectors,transits,BLS,model,FFI
128703021,"11,38","1601.85,2342.27",no,0,no

It failed after downloading the lightcurve fits files.

$python -m LATTE --targetlist=dataLATTE/input128703021.csv

TIC 128703021 failed to complete. Continue anyway. You can find a list of the failed IDs stored in the output folder.

• I can create a DV report if I use the GUI (with a local fix of Regression: _aperture_size.png is not created/saved when multiple transits are specified. #39)
• If I specify only 1 sector and 1 transit in the csv file, it launches the GUI due to issue batch mode still interactively showing plots when a single transit given #13
• There is no specific error stacktrace I can get due to issue Error reporting - no output on the reasons of the error in batch mode #15 .
