Bump version for picky-asn1 to avoid rust incompatibility warnings

In a project with tss-esapi as a dependency, I'm getting this warning on
my builds since rust 1.90:

```
warning: the following packages contain code that will be rejected by a future version of Rust: picky-asn1-x509 v0.12.0
```

The latest versions seem to compile cleanly and works for me.
