README usage section is outdated #414
Description
While creating #413 I've noticed that the README usage and the output of gdu -h (v5.30.1) differ.
E.g.
gdu [directory_to_scan] [flags]
in the output of gdu -h and
gdu [flags] [directory_to_scan]
in the README
or
-i, --ignore-dirs strings Absolute paths to ignore (separated by comma) (default [/proc,/dev,/sys,/run])
in gdu -h and
-i, --ignore-dirs strings Paths to ignore (separated by comma). Can be absolute or relative to current directory (default [/proc,/dev,/sys,/run])
in README
I'm assuming the CLI output is (more) up-to date in which case I'd suggest updating the README usage accordingly.
