change(deps): upgrade zcash_script and zcash dependencies

[conradoplg]

Motivation

See #4767

To do that we must update zcash_script and related dependencies.

Specifications

Designs

Solution

Update zcash_script which allows us to upgrade the zcash dependencies.

Updates zcash_proofs to upstream again and not our fork, after the Sprout params downloading code was merged.

Closes #4767

Review

This PR is blocked on:

• Update to zcash 5.2.0 zcash_script#37 being accepted, a release being made, and changing this PR to point to it
• zcash_proofs being released so that we don't depend on a git commit, which will allow us to remove duplicated dependencies (optional; we may skip this if we want) This may take a while so let's not wait for it

Reviewer Checklist

• Code implements Specs and Designs
• Tests for Expected Behaviour
