Pin winnow and inferno dependencies to resolve version and compilation conflicts

[dmidem]

This PR addresses build issues within the librustzcash repository.

In the zcash_history crate, the winnow dependency has been pinned to an older version. The latest version of winnow enforces the use of Rust v1.64.0, but the zcash_history crate is tied to Rust v1.61.0. This mismatch was causing build problems, which have now been resolved by this change.

The inferno dependency, which is used in the zcash_proofs crate among possibly others, has also been pinned to an older version. The latest version of inferno (0.11.15) was causing a compilation error. By pinning it to version 0.11.14, this issue has been resolved.

These changes are temporary fixes, and should be revisited once the Rust version used in the librustzcash repository is updated or the dependencies resolve their respective issues.

These fixes resolve the problem with winnow and inferno, but there is another issue when CI checks the repo.

It logs an error: "Input required and not supplied: path" for actions/cache@v3.0.11 GitHub action, and here's a possible place in .github/workflows/ci.yml that causes the issue:

      - name: Cache Zcash parameters
        id: cache-params
        uses: actions/cache@v3.0.11
        with:
          path: ${{ env.ZCASH_PARAMS }}
          key: ${{ runner.os }}-params

It's possible that the ZCASH_PARAMS variable is not defined in the repo settings (environment).

UPDATE:

It seems that the "Input required and not supplied: path" error disappeared after I made fixes to resolve dependency issues. Therefore, it passes all CI checks now.
