Allow ability to use json tag to get lower case names

[kyprifog]

Structs in Go have to have upper case names in order to be public but in json you can get around this by passing the tag: `json: name_lower`

Is there a way to do something similar with faker so that field names don't have to always be upper case?

Hmm.. interesting.

I haven't tested it yet. Have you tested it?

I wonder if that's possible, but it will need time to research this. I might need someone's help if possible. If not, I will take a look at this when I'm free.

FTR I tried that but it didn't work, id have to spend a bit more time knowing how the library works to know if it made sense for it to work. I want to just be able to produce fake data with a lower case character. May be other ways to achieve the same result.
