* feat(barchart)!: render the group labels depending on the alignment
This is a breaking change, since the alignment by default is set to
Left and the group labels are always rendered in the center.

for now the value is converted to a string and then printed. in many
cases the values are too wide or double values. so it make sense
to set a custom value text instead of the default behavior.
this patch suggests to add a method
"fn text_value(mut self, text_value: String)"
to the Bar, which allows to override the value printed in the bar

* Fix barchart incorrectly showing chart filled more than actual
Determination of how filled the bar should be was incorrectly taking the
entire chart height into account, when in fact it should take height-1, because
of extra line with label. Because of that the chart appeared fuller than it
should and was full before reaching maximum value.
* Add a test case for checking if barchart fills correctly up to max value
