support regex to source argument in command
I want to read all svg files in all folders in root folder and 
I must use regex in source argument in command.

my command is  :  " svgtofont --sources icons/svg/**/*.svg --output icons/font "

but command argument not support regex and give "The directory does not exist! C:\icons\svg\**\*.svg" this error!

can support regex for this command ?
