Lognet

fix cyclical dependence of imports

added docstring and update setup.py: u can install package

The singleton pattern has been removed for now to implement the future idea of ​​routers, where several instances of the class will have to be created, or the logging levels will be redesigned. In any case, the singleton will (most likely) not be used anymore. A springboard has been created for implementing filtering of existing logs using a database.

Complete code change. Added formatting instead of flags. Removed: color console and asynchronous version.

Added asynchronous version of logger

Added documentation and fixed a bug with formatter processing (time and date)
