Final trail in twooffive barcode interleaved is shorter

[dev-gto]

Some readers are getting confused while (not) reading the stop pattern.

Currently the component renders the sequence: black bar (2 dots wide), white bar (1 dot wide), black bar (1 dot wide).

I think it should be: black bar (3 dots wide), white bar (1 dot wide), black bar (1 dot wide).
