In most cases 'fwupdtool firmware-dump' and 'fwupdtool firmware-read'
are going to be the same. This isn't true in all cases, especially when
dealing with composite firmware like archives.

When developing code it's really convenient to only run the new plugin. This
means you don't have to wait for the other hardware to initialize and there
are no side-effects from other plugins when installing firmware.
You can specify multiple plugins as globs, for instance:
fwupdtool get-devices \
--plugin-whitelist wacom \
--plugin-whitelist "thunderbolt*"
