old version of go-tpm-tools

This project depends on a rather old version of go-tpm-tools (v0.3.13 from June 2023).

I ran into CGO issues on macOS when using the simulator from go-tpm-tools. The older v0.3.13 version has hardcoded OpenSSL paths that don't work out of the box, but v0.4.5 fixes this apparently.

The problem is that go-tpm v0.9.7 depends on v0.3.13:

```
github.com/google/go-tpm-tools v0.3.13-0.20230620182252-4639ecce2aba
```

This means even if I add go-tpm-tools v0.4.5 to my go.mod, Go's MVS picks the older v0.3.13 because of go-tpm's requirement.

Could you update the dependency to v0.4.5?

Start with go.mod and inspect the go-tpm v0.9.7 requirement for go-tpm-tools. Update the dependency so the module graph selects v0.4.5, then verify the resolved version and confirm the macOS simulator dependency issue is addressed.
