deps: update secp256k1 to 0.31

[dshulyak]

using newer secp in the authentication protocol, there were some changes in api.
also erase can be now used on inner type without additional unsafe block

The base branch was changed.

[dshulyak]

wasm compilation is broken in 0.31. looks like version bump is blocked until new secp version is released that will include this fix rust-bitcoin/rust-secp256k1#818

[omegablitz]

Weird, secp shouldnt be a transitive dep in the wasm build. That seems unintended.

[omegablitz]

It's because of this in monad-eth-types:

pub trait ExtractEthAddress {
    fn get_eth_address(&self) -> Address;
}

impl ExtractEthAddress for NopPubKey {
    fn get_eth_address(&self) -> Address {
        Address::new([0_u8; 20])
    }
}

impl ExtractEthAddress for SecpPubkey {
    fn get_eth_address(&self) -> Address {
        Address::from_raw_public_key(&Self::bytes(self)[1..])
    }
}

moved implementation of ExtractEthAddress for Pubkey to monad-secp to avoid secp imports in monad-eth-types
