cam: options: Fail parsing when non-option arguments are found
The options parser currently ignores non-option arguments silently,
which is confusing. It's a common error to run 'cam -c1 -C 10' and
expect only 10 frames to be captured. As the -C option takes an optional
argument, the number 10 is interpreted as a non-option argument instead
of the argument to the -C option.
Fail parsing with an appropriate message and print usage information
when a non-option argument is found. The parser may be extended later to
accept non-option arguments when the application has a use for them.
