cam: Allow selecting cameras by index

As camera names can be cumbersome to type, selection of cameras by index
from a list can be useful. Print the list of detected cameras with an
index for each item, and interpret the camera name as an index if it is
a numerical value in the range from 1 to the number of cameras.
