increase length of some string fields

[hoannv]

Hello @TiagoBrito @alexanderdean @yalisassoon,

We have an issue related to length of some string fields. Field's length is too short. So some strings are cut when saving into database.

I update code and create a pull request. Pls review and merge.

Hi! We are not actively maintaining this library. Happy to transfer it to a good home

@alexanderdean It would be great if you merge it, because we use this package in some projects. It helps us save time for updating a small issue

Sorry I can't merge code that I haven't reviewed, and I can't review code that I'm not actively maintaining.
