Replace visualreport by a report that aligns with the rest of GGIR

[vincentvanhees]

The visual report is known to not match what GGIR does and we warn about this in the documentation, but someone it continues to cause confusion and raise questions. So, the visual report function (plot5) should be replaced to better match the actual classification of GGIR.

Part of the problems are:

• Wake up classification on first morning after an incomplete night done but not visualised.
• A lot of functionality duplicated and possible inconsistent with the main GGIR code.

Outstanding work:

• Indicate whether window met inclusion criteria => not logical, because this decision happens afterward
• Make it easier to skip windows that do not meet inclusion criteria => not logical, because this decision happens afterward
• Rename function and report to emphasize that it is for QC purposes => now clarified in documentation
