Blackbody crashes on some thermogams

Notably, those from ThermoCam B400 and E40.

Error for E40 is the following:

thread 'main' panicked at 'slice index starts at 38912 but ends at 2476', /[..]/flyr-0.4.0/src/lib/flyr.rs:145:30
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Which corresponds to these lines in flyr, specifically line 6’s &bytes[start..end]. I doubt this line is wrong, otherwise other thermograms would fail to load. Perhaps for these models, the length is stored differently.

fn parse_camera_info(
    bytes: &[u8],
    metadata: &FlirRecordEntryMetadata,
) -> Result<FlirCameraInfo, io::Error> {
    let start = metadata.offset as usize;
    let end = metadata.length as usize;
    let camera_info_bytes = &bytes[start..end];

    match Cursor::new(camera_info_bytes).read_be::<FlirCameraInfo>() {
        Ok(camera_info) => Ok(camera_info),
        _ => Err(io::Error::new(io::ErrorKind::InvalidData, "Failed reading FLIR image's camera info")),
    }
}

Error for B400 is the same, probably the same issue:

thread 'main' panicked at 'slice index starts at 154720 but ends at 2476', /[..]/flyr.rs:145:30

Due to unwraps for camera model S60 NTSC:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: ShapeError/IncompatibleShape: incompatible shapes', /[..]/flyr-0.4.2/src/lib/flyr.rs:239:45

Issue resolved for the B400 and E40. Lost the S60 camera examples, so can’t test with those anymore.
