tcam-ctrl: --load accepts files
tcam-ctrl: --load accepts files

--save and --load cannot be made compatible due to the fact that
'{' and '"' are special characters in bash that have to be escaped to be
correctly passed to the program. --load now checks if the given argument
is a valid file path an attempts to load the file content as json.

Usage: tcam-ctrl --load <SERIAL> <FILEPATH>
