Always use 0 section. Error when sections more than 1

[ZhurbiloYaroslav]

Hello Dear Kiran!

Thanks for your awesome library!

I have found that you always use 0 section.
In my project there is 3 sections and was a bug.

I have found that in lines:
line: 442

• was: let indexpath: IndexPath = IndexPath(row: row, section: 0)
• now: let indexpath: IndexPath = IndexPath(row: row, section: indexPath.section)

and
line 454:

• was: let indexpath: IndexPath = IndexPath(row: updateStateOfRow, section: 0)
• now: let indexpath: IndexPath = IndexPath(row: updateStateOfRow, section: indexPath.section)

Would you be so kind and fix this bug

Thanks in advance!
