Camel case not working as expected for fields with numbers

[jdnichollsc]

Hello folks, hope you're doing well

Thanks for creating this community tool, that's awesome! I tried this tool but I'm getting errors with fields that includes numbers, e.g:

address_line_1
address_line_2

and after executing this tool, this is generating this:

addressLine_1
addressLine_2

but I was expecting this other format instead:

addressLine1
addressLine2

Is there any option to fix this bug?

I'm trying to fix this issue from a fork in the meantime, but any help is really appreciated! <3
