Update secp256k1 to latest

[LuKks]

Closes #204

I couldn't fix this error:

node:internal/modules/cjs/loader:1465
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

}

Node.js v20.12.2

This looks somewhat related bitcoin-core/secp256k1#1181 but I don't know about C, bindings, or any of this so any hints would be appreciated, thanks

The error might be caused by a breaking change in libsecp256k1 v0.4.0:

When consuming libsecp256k1 as a static library on Windows, the user must now define the SECP256K1_STATIC macro before including secp256k1.h.

I can get around this error by unconditionally defining variables as static in precomputed_ecmult_gen.h and precomputed_ecmult.h, but it's not clear to me why EXHAUSTIVE_TEST_ORDER isn't being set correctly.

The upstream lib is now at version 0.6.0, so this should be rebased.
