Logging module for OCaml.

Quick start :

open Easy_logging
logger = Logging.make_logger "my_logger" Debug [Cli Debug];;
logger#info "log_message";;

See documentation at https://sapristi.github.io/easy_logging/easy_logging

printf style logging is now the default
simplifed configuration in case of multiple loggers (and closer to the python module) : the loggers form a tree (based on their name, dots indicating descendence)
- log items are passed to the handlers of a logger’s ancestors (so that few handlers need initialisation) (possible to override)
- loggers inherit the level of their ancestor if not set explicitely
an additional package easy_logging_yojson provides initialisation of loggers from the json format (with ppx_deriving_yojson), so that configuration can be fully done outside the code.

Renamed the Default_handlers module to handlers
tag type in Handlers is now string (was unit)
added the possibility to add filters to handlers
added tag_generator feature to loggers, to automatically add tags to all messages passed to a logger

log_level type is direcly accessible from Easy_logging and Easy_logging_yojson modules

Added more options to file handlers (automatic timestamps and/or versioning of file names)
Added CliErr handler to output to stderr
modified handlers type so that fully custom handlers can be instantiated
cleaned module API
log items contains a timestamp
