Update rollup script to exclude new secp256k1 and hmac/sha256 dependencies

[steveluscher]

Problem

I always forget to do this, and there's no static analysis to stop this mistake from being made.

Summary of Changes

Test plan

yarn build

Inspect ESM bundles in /lib/. Observe that @noble/hashes and @noble/secp256k1 are no longer inlined.
