Can't run script from the folder with loaders, that doesn't contain mot/ directory

[rshym]

It's quite possible use case, to have separate folder with the loaders (../build_domd/.../images/...) and separate folder with the rcar_flash in different places.
It could be great to go to the folder with the loaders and run the command <path_to>/rcar_flash.py list-boards or <path_to>/rcar_flash.py flash ....
But in this case rcar_flash reports error
rcar_flash.py: error: argument --conf: can't open 'rcar_flash.yaml': [Errno 2] No such file or directory: 'rcar_flash.yaml'

It could be great, if rcar_flash will look for the mot/ directory in the local directory, and then in the directory it was started from.
