### Description This adds an external function to the OracleAdapter to be able to check the status of a chainlink sequencer uptime data feed. We will use this in the bold repo to ensure that liquidations can only happen when the sequencer has been up for at least a certain grace period. See https://docs.chain.link/data-feeds/l2-sequencer-feeds for more context I decided to leave the ability of setting the l2SequencerUptimeFeed to address(0), in case we ever want to disable this check for any reason. Related PR in the bold repo: mento-protocol/bold#33 ### Tested Added some basic unit tests. Will add integration tests once the bold repo PR is merged

This PR in combination with mento-protocol/mento-core#682 disable liquidations in the event the L2 sequencer is down or had a very recent recovery.
The idea is that if the sequencer were to go down, non-technical users have a higher risk of facing liquidation, since they wouldn't be able to easily add more collateral to their troves if needed. By disabling liquidations/giving a grace period to act in such a scenario, we make the playing field more fair for everyone.
