In avifenc/dec, treat all arguments that start with '-' as flags.

To pass filenames that actually start with '-', users can either
prefix the path with './' or use '--' to signal the end of flags, e.g.
./avifenc --min 0 --max 63 -- --my_input.png output.avif

This creates clearer error messages, e.g.
avifenc input.png output.avif --badflag
would print 'Unrecognized file format: output.avif' but now prints
'ERROR: unrecognized flag --badflag' instead.
