Panic when attempting to decode an empty image as a "pure barcode"

[dlenski]

Attempting to decode an empty image (e.g. https://github.com/dlenski/python-zxing/blob/master/test/barcodes/empty.png) as a pure barcode results in a panic at https://github.com/rxing-core/rxing/blob/v0.6.2/src/oned/one_d_reader.rs#L190

Example with rxing-cli:

$ rxing-cli test/barcodes/empty.png decode --pure-barcode true
thread 'main' panicked at /home/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/rxing-0.6.2/src/oned/one_d_reader.rs:190:17:
index out of bounds: the len is 0 but the index is 0
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

In non-pure-barcode mode, it gives a more usual NotFoundException:

$ rxing-cli test/barcodes/empty.png decode --pure-barcode false
Error while attempting to locate barcode in 'test/barcodes/empty.png': NotFoundException
