More log levels

Adds TRACE and INSPECT PROFILE log levels.

Any better name for a level between DEBUG and TRACE? Maybe PROFILE? (see suggestion below)

I'd suggest the following guidelines:

• INFO: not used internally, reserved for module developers (maybe log top-level scheduler stuff here, like start of initialize, connect, run, finalize?)
• PROFILE: logging for stuff that might impact performance, like unit conversions, storing slot data to disk, ...
• DEBUG: current logging of the scheduler, components and adapters
• TRACE: current logging for everything below components (i/o slots, connector, ...)

Distributed the logging over more levels.

INFO: top-level scheduler events

2022-12-08 14:55:30,440 INFO: finalize composition                 - FINAM

PROFILE: like INFO, but reports file access and unit conversions (could add more performance-related stuff)

DEBUG: Component-level information:

TRACE: Everything, just like DEBUG before this change.
