* Updated go-ethereum dep to 1.10.21
* Code now installs/uses an abigen that automatically matches the version of our go-ethereum in the go.mod
* solc was updated to 0.8.16 (in the docs, we don't install it, but anyone wanting to generate identical output needs it).
* Minimum go version is now 1.18
* golangci-lint updated to v1.48.0 (was needed to play nicely with go 1.18 and the new generated code)
* dleq/cgo-dleq submodule updated to latest version
Updates the repo to install the latest version of ganache (ganache-cli is obsolete).
One of the things that changed in the newer version of Ganache, is gas fee estimation uses the timestamp from the last mined block instead of the local computer's current timestamp. This mirrors what Geth does, so the Ganache change is helpful, but it caused a few problems that this PR fixes.
If we want to do dynamic fee estimation for a transaction that can not happen before time T0 or T1, we need to wait until there is one mined block after T0 or T1 to create our transaction. Otherwise the transaction will be reverted during fee estimation, returning an error when creating the transaction, and we'll never send the transaction out to the network.
Ganache, by default, only mines blocks when you create a transaction. In order to have a mined block after T0 or T1 to calculate transaction fees, we stopped using instamine, and now mine a block every second. This PR chose the minimum block interval for speedier tests.
