The west bindesc command currently crashes when no subcommand is
given. This is because the subcommand was not marked as required.
This commit fixes the issue.

Added the bindesc command to west, for working with binary
descriptors. Currently it supports dump, list and search
subcommands, for bin, hex, elf and uf2 file types.
