Sirilic Argument Error weight_from_wfwhm

Having problems with Sirilic stacking on Mac (not sure if platform dependent) since the 1.4.0-beta1 update. Same project that stacked fine yesterday on previous Siril version is failing today on the following:

log: Running command: stack
7: running command stackReading sequence file `r_image_group_.seq'.
bitpix for the sequence is set as 20
log: Unexpected argument to stacking `-weight_from_wfwhm', aborting.
log: Error in line 346 ('stack'): invalid arguments.
stack r_image_group_ mean w 3.000 3.000 -weight_from_wfwhm -norm=mulscale  -out=../Ha

It seems that there has been a change in argument handling in the newer version of Siril but I cannot confirm this.

I switched Weighing to None and it completed successfully, so definitely something with the `-weight_from_wfwhm’ argument.

Editing the script to use -weight=wfwhm fixes the issue. Thanks to some discussion on Discord to find out what the correct argument should be.
