[Feat] Configure structlog properly as quantumvim dependency

[quantumfate]

The code of quantum vim has grown too big so has the amount of log messages. Due to the use of only one logger factory message reports became redundant. Logging an entry at the error level for example causes the message to appear in any sink that is below error as well. Therefor each sink causes an entry to be logged.

• add structlog as a dependency (Has to be in runtime path from the start [Feat] Runtime path modifications and user config after directory #7 )
• update the install script to dowload structlog on install in the pack directory
  • ensure lazy can pick up structlog for updates
• implement multiple log factories as logical pieces
• provide multiple log files as logical pieces (eventually seperated in directories, depending on the amount of sinks/factories)
