feat(barchart): set custom text value in the bar (#309)
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 Signed-off-by: Ben Fekih, Hichem <hichem.f@live.de>
