Change to having one record file per day and rewrite file access infrastructure to serve this.

I believe this is a useful improvement. The main two advantages are that a) it is very cheap to check whether a record exists for a given day - just check for file presence and b) there is a reasonable limit to the size of these files (never more than a few hundred records per day) which means that they can just be loaded into ram for processing without any complex splitting operations
Currently, the necessary `~/asteroid-healthloggerd/stepCounter` and `...loggerd/heartrateMonitor` directories are not automatically created and the code just vomits errors into log if it can't write to them.
