🦋 OPTIONAL ARGUMENTS 🦋

• -h, --help — show a help message and exit. classic. iconic. never misses. ⭐
• --dwelltime DWELLTIME — specify a new dwelltime (1/bandwidth, pixdim[4]) value in seconds. yes, seconds. don't come at me with milliseconds, i don't make the rules. 😭
• -f FILEOUT, --fileout FILEOUT — output file base name (default = input file name). so if you don't say anything, she just names it after the input file. lowkey polite of her. 🌸
