COMP: Ensure CLIExtensionTemplate download all associated external data

From ExternalData.cmake documentation:

# The DATA{} syntax can alternatively match files associated with the named
# file and contained in the same directory.  Associated files may be specified
# by options using the syntax DATA{<name>,<opt1>,<opt2>,...}.  Each option may
# specify one file by name or specify a regular expression to match file names
# using the syntax REGEX:<regex>.  For example, the arguments
#   DATA{MyData/MyInput.mhd,MyInput.img}                   # File pair
#   DATA{MyData/MyFrames00.png,REGEX:MyFrames[0-9]+\\.png} # Series
# will pass MyInput.mha and MyFrames00.png on the command line but ensure
# that the associated files are present next to them.
