Bump bpaf to fix the broken completions

[dgudim]

In some cases completions broke for me (albeit, when i was misusing them, but still a bug). Turns out it's a bpaf bug.

Original issue: akinomyoga/ble.sh#368

It was already reported to bpaf, we just need to wait

Is it this bpaf issue that I reported or yet another one? If so, could you link it here so I can keep track of it.

Hm, seems to be a different one: pacak/bpaf#311

I don't use bash so I wouldn't have noticed it. It would be great to have tests of the completion that bpaf outputs somehow, but it seems quite complicated. Especially since executing the binary from tests tend to break when cross compiling.

0.9.6 is out

[VorpalBlade]

This will be included 2.2.0 that is being built as of writing this.

Note that the actual completions themself are still broken pending @pacak fixes pacak/bpaf#303 (no pressure). But at least it should just do nothing instead of error out.

Though I haven't tried this with bash, as I'm not set up to test that. I would like to add auto tests for the completion at a future point, probably once the above mentioned issue is solved (would be kind of pointless while it is still broken).
