mod: update to faster go-ipa

[jsign]

This PR updates our go-ipa dependency to current master.

It has improved the proving generation and verification speed due to a bunch of PRs:

• https://github.com/crate-crypto/go-ipa/pull/39
• https://github.com/crate-crypto/go-ipa/pull/40
• https://github.com/crate-crypto/go-ipa/pull/41
• https://github.com/crate-crypto/go-ipa/pull/42
• https://github.com/crate-crypto/go-ipa/pull/43
• https://github.com/crate-crypto/go-ipa/pull/45
• https://github.com/crate-crypto/go-ipa/pull/46
• https://github.com/crate-crypto/go-ipa/pull/48
• https://github.com/crate-crypto/go-ipa/pull/49

Here's a "before" and "after" comparison generated by vkt-proof-bench:

• Before
• After

All applied optimizations were collected in a more technical doc here.

I did the summary above to explain what happened behind the dependency update comprehensively. For go-verkle, this dependency update is transparent since it doesn't affect APIs or require extra assets.
