Switch to custom chain id

[matstyler]

Use case

I add new, custom network (with custom network id):

return Web3Mock.mock({
          blockchain,
          wallet,
          network: {
            add: networkInfo
          }
        })

Then I want to switch to that network:

Web3Mock.mock({
          blockchain,
          wallet,
          network: {
            switchTo: networkName
          }
        })

        window.ethereum.request({
          method: 'wallet_switchEthereumChain',
          // Mock do not support custom network IDs
          params: [{ chainId }]
        })

Unfortunately switch to custom chan id is not working as @depay/web3-mock support only existing chain ids.
