parsers/hdrext: Parse the @id as u16 instead of String

Browse source 
The specification says it can only be in the 1-256, 4096-4351 ranges, so
use the closest type available.  This doesn’t validate that the value is
correct, but that will be done in a future commit.

Thanks gst-meet for making me notice this issue!
