QZXingFilter: Enforce captureRect validation
...
captureRect is accessible and modifyable via QML, so that
it can take arbitrary values, what can make QZXingFilter to crash
the application.
This issue was experienced when running code similar to QZXingLive
example on an android device, where captureRect is bound based on
VideoOutput's contentRect and sourceRect, when QML Engine is
calculating layout for the pages it sets temp values to width/height
of elements (including VideoOutput) what causes captureRect to be
set to invalid values for the QZXingFilter's perspective, such
as negative values for x and y.

QZXingFilter: Fix crash when destructing QZXingFilter
...
QZXingFilterRunnable runs QFuture to perform
decoder::decodeImage() and stores it in a
class var of its owner (QZXingFilter), but
when QZXingFilter is destructed it was not canceling
that QFuture, making possible to the QFuture to try to
access filter->decoder->decodeImage() after filter's
are already destructed (dangling pointer).
Issue detected when using QZXingFilter QML Element in
an Page pushed in a StackView. When the page containing the
QZXingFilter is poped from the StackView, (by default) the
filter is unloaded/destructed, what makes the app crash
without this patch.

The filter is much more performant than using the QZXing API in an
imparative way for the use-case of live-analyzing video frames in QML.

This again leads to a noticeable performance improvement of the

converting to RGB and then converting to greyscale.

Add captureRect functionality

This allows one to only detect within a certain unscaled region
of the input frame. The reduction of pixels scanned leads to
a significant performance win, and the removal of the scaling
improves the quality of the checked image, thereby leading to
higher detection rates.
