Calling Secp256k1::randomize on a verification-only context will abort the process #82
Description
TIL that secp256k1_context_randomize actually requires a signing context, despite the docs not mentioning this. See bitcoin-core/secp256k1#573
The following code can trigger a process abort in a unit test (run with cargo test --features "rand")
