Can't use scroll controller

[YahyaYousef]

CustomRadioButton did not include scrollController to handle scrolling programmatically @ketanchoyal @omar-hanafy @patuoynageek @guissalustiano

This shouldn't be hard to add, never had any usecase until now, anyways I'll add this feature soon.

Thanks for using this package

@ketanchoyal The case was when using this package with windows in new flutter version I cant scroll horizontally without scrollbar please add this feature ASAP

@YahyaYousef sure I'll add it asap, or I'll appreciate it you can make a PR for it

Thanks
