Add QCategoryAxis as a time axis for QCandlestickSeries

I'm using an approach similar to TradingView's Lightweight Charts for drawing nice numbers for time values. It has one so-called logical axis, a float axis whose round values correspond to the indices of a data set and indicate current zoom and pan levels. I compute a tick interval and a tick anchor and attach category labels (with time values) where I need to draw them. And I can skip weekends and non-trading hours as well as opposed to QDateTimeAxis. I've attached the screenshot, how it looks.

All is needed from you is to add one line

case QAbstractAxis::AxisTypeCategory:

here:
https://code.qt.io/cgit/qt/qtcharts.git/tree/src/charts/candlestickchart/candlestick.cpp?h=v6.2.0-beta3#n239

Currently I'm using an ugly hack, I've created a QCategoryAxis subclass and overridden the type() method, where I just determine with __builtin_return_address(0) and dladdr the calling function and if it is the Candlestick::updateGeometry I return AxisTypeValue, otherwise the behaviour is default. Technically it works but it depends on the private code changes.
