3221: Light Mode: Time Interpreter r=Unisay a=Unisay ### Issue Number ADP-1422, ADP-1505 ### Overview [Light-mode][] (Epic ADP-1422) aims to make synchronisation to the blockchain faster by trusting an off-chain source of aggregated blockchain data. [light-mode]: https://input-output-hk.github.io/cardano-wallet/design/specs/light-mode In this pull request, we implement a function `timeInterpreter` that allows wallet to convert between relative blockchain time (epochs, slots) and absolute wall-clock time. To make such conversions correct `TimeInterpreter` needs to take into account historical values for various protocol parameters as well as past hard forks. Unfortunately Blockfrost API doesn't expose required functionality. We therefore hardcode summary information about past hard forks that happened on the Mainnet.
