This commit adds a chanfitness package which will be used to track channel health and performance metrics. It adds a channel event structure which will be used to track channel opens/closes and peer uptime. The eventLog implements an uptime function which calcualtes uptime over a given period and a lifespan function which returns the time when the log began monitoring the channel and, if the channel is closed, the time when it stopped moitoring it.
