New alive-progress 3.0

[rsalmei]

Yep, I could finally get this version out! These are the new goodies:

• Units support! You can now label the data you're processing, like B, bytes, or even °C!
• Automatic scaling! With support for SI (base 1000), IEC (base 1024), and even an alternate SI with base 1024, you'll be well served!
• Configurable precision! When your numbers are scaled, you get to choose how many decimals they display!
• Automatic stats scaling for slow throughputs! If your processing takes minutes or more, now you'll see rates per minute, per hour, and even per day! (It works within the auto-scaling system!)
• Support for using sys.stderr and other files instead of sys.stdout!
• Smoothed out the rate estimation with the same Exponential Smoothing Algorithm that powers the ETA, so the bar returns a more realistic ETA!
• Query the currently running widgets' data, like the monitor, rate, and ETA!
• New help system on configuration errors, which explains why a value was not accepted, and what were the expected ones!

Highly anticipated fixes

• Support for reusing logging handlers! No more TypeError: unhashable type: 'types.SimpleNamespace'.
• Support for logging when using RotatingFileHandlers! Yep, seek support is here.
• Fix unknown mode always ending with a warning (!)

Code coverage has improved a lot
