LMC v5 - log file format changed (#1)

A set of breaking changes for LM Challenge version `5.0`. We have redesigned the log format, and extended some of the utilities, documentation & testing (although there is more to be done). A non-exhaustive list of changes:

 - new log file format (see doc/formats.md)
   - flatter
   - more regular
   - easier to load
 - `lmc pretty` utility split into `pretty` (for a single log) and `diff` (for comparing logs)
 - `lmc grep` added, to replace & extend the filtering functionality throughout other utilities
 - migrated documentation from Spinx to pdoc
 - migrated tests from nose to pytest
 - freeze `requirements.txt` by default
 - simplify `stats` implementation from `Monoid` to `Accumulator`
