Change config.escape_keywords to AfterConvertingCase.
It avoids unecessay escaping since the generated native
structs have fields starting with a uppercase letter
and Go's keywords start with lowercase letters.

* [golang] Add support for text parsing with json struct tags
Add struct tags to Go native structs generated when object API is used.
This allows to use the same JSON file as for C++ text
parsing(i.e. snake_case vs CamelCase) and thus enabling text parsing
for Go(when using object API).
* [golang] Add test for text parsing
Added small test to check and demonstrate text parsing in Go.
Also, ran clang-format on cpp file changes.
