Camera model changes:  o MVX100i/Optura 20 is now 0x3082, not 0x3081.  o PowerShot A75 moved from class 5 to class 1 as a guess. Allow unexpected length of packet returned from "get picture abilities". Made canon_int_capture_preview() more like canon_int_capture_image(). A bit of housekeeping here and there.
