Unable to show total Text labels in Stacked Bar Plot

[RaginBajin]

Is this a BUG REPORT or FEATURE REQUEST?:

Type: bug

Environment:

• Chartify version(s): 2.6.0
• Operating System(s): OSX
• Python version(s): 3.6.7

What happened: Unable to show total label count in a stacked bar plot when using: text_stacked

What you expected to happen: Like .text, I should be able to just have the total for that particular stack instead of the individual stack counts.

Example: Bar has two stacks - 37 Male, 63 Female. Instead of seeing 37 and 63 inside each of the specific stacks, I should be able to see 100 at the top of the stack just like in a normal bar plot.

How to reproduce it (as minimally and precisely as possible):
