✨ Support for unpacking local image - tar files

[santhoshdaivajna]

Is your feature request related to a problem? Please describe.
luet util unpack currently does not support extracting image files from the filesystem and requires docker daemon on local.

Describe the solution you'd like
take image file path as an input and extract the content to destination path.
ex: luet util unpack file://home/us/alpine.tar /tmp --local

Describe alternatives you've considered

Additional context
It would help remove the dependency on docker daemon when images files are available on the host system.
