Flow Button Bar - Increase maximum number of buttons

[RealEvanPonter]

Is your feature request related to a problem? Please describe.
I'd like to create a Net Promoter Score question on a flow screen with selectable options 0-10 (i.e. 11 options). Vertical radio choices consume a lot of real estate. I realized that the "Selection" mode of Flow Button Bar achieves the desired experience, but currently Flow Button Bar is limited to 5 buttons per component. This is a hard-coded limit on line 172 of fsc_flowButtonBarCPE.js. I propose removing this limit entirely or updating the hardcoded limit to at least 12 (I'm not sure how many buttons could be supported in a horizontal layout if long labels are used).

Describe the solution you'd like
Allow for unlimited (or at least 12) buttons to be configured in a single Flow Button Bar component

Describe alternatives you've considered
I've manually adjusted this limit in my client's org, but fear the change will be overwritten if anyone updates the package in the future

Additional context
There is currently no standard screen component that allows for a horizontal display of selectable choices. Updating this hardcoded limit would allow for a really easy win to facilitate NPS, CSAT, Likert Scale, and other common survey question input formats.

Example desired configuration for an NPS Score question:

Hi, Evan! So you've tested it out with the higher number and it seems to be ok? It feels like a low risk thing to change....

Yes, more than 5 buttons functions as expected. I have a screen full of 12 button questions working great.
