change(nu5): update librustzcash

[conradoplg]

Motivation

zcash_script has a new API due to ZIP-244 changes that we must use.
In order to use it, we also need the updated librustzcash which also had API changes.

Specifications

Designs

Solution

• Change to work with new librustzcash API
• Fix dependency versions

Split from #3799
Part of #3520
Closes #3056

Review

This was split from #3799 which was reviewed by @teor2345

This is blocked on ZcashFoundation/zcash_script#30 (which is also blocked) so it's a draft, but it can already be reviewed.

This blocks the testnet reactivation test, so it's important.

Reviewer Checklist

• Code implements Specs and Designs
• Tests for Expected Behaviour
• Tests for Errors

I think some of the dependencies might be wrong?

The application panicked (crashed).
Message: zcash_script_new_precomputed_tx returned 4 (encountered unknown error kind from zcash_script: 4)

[teor2345]

I'm happy with this, as soon as the tests pass.

I'm happy with this, as soon as the tests pass.

It turns out we couldn't split the PR since we feed V5 transactios to zebra_script when testing, and zcash_script won't accept them in the pre-V5 functions 😢 I'll close this and change #3799 to target main again
