discovery+lnd: create new chanSeries impl of the ChannelGraphTimeSeries interface

Browse Source 
In this commit, we create a new concrete implementation for the new
discovery.ChannelGraphTimeSeries interface. We also export the
createChannelAnnouncement method to allow the chanSeries struct to
re-use the existing code for creating wire messages from the database
structs.
