To dump the DB, the service must be stopped.
If this is not the case `dump` command just hangs without any output,
which _may_ be unexpected from the ops POV.
Introduce a 1 second timeous, which is more than enough, given
that bbolt retries doing flock() every 50ms.

Currently we take int64 value from the Go parser and push it to the
stack. Using uint64 is not a common practice (usually we just use `int`),
but can be a problem while doing bit arithmetic and serializing numbers.

And ignore on dependency checks, we update all the examples at once
anyway, so may safely skip the check for zkp folder.

An upgrade from gnark v0.8.X to v0.9.0 changes serialization format of verifying/proving keys
and proofs. In neo-go zkpbinding package we have to support both at least for now, because
gnark@v0.9.0 requires minimum go 1.19.

The example shows that the proover knows the solution of the cubic
equation: y = x^3 + x + 5. The example is constructed for BLS12-381
curve points using Groth-16 prooving algorithm. The example includes
everything that developer needs to start using ZKP on the NEO platform
with Go SDK:
1. The described cubic circuit implementation.
2. The off-chain proof generation with the help of gnark-crypto library.
3. Go verification contract generation and deployment with the help of
NeoGo libraries.
4. The on-chain proof verification for various sets of input data.

Valid transactions can't use more than MaxVerificationGAS for script execution
and this applies to the whole set of signers, so use this value by default
unless local instance configuration suggests something lower for generic
invocations.

We can ignore core.ErrInvalidSignature (which means that the script has
executed, but returned false), but we shouldn't ignore other errors which
likely mean that the script is incorrect (or hits some resource limits).
Use neorpc.ErrInvalidSignature as a return to separate this case from
contract-based verification.

It requires explicit signers, and we have a problem with the old code:
