Expose sass2scss function
Some background: I want to support mixed scss and sass codebase with a custom importer. My importer passes the file contents as string to Import. Libsass converts sass sources to scss on read_file function: https://github.com/sass/libsass/blob/4869c0fb3abeb4697959a415ccc2fc6aec290378/src/file.cpp#L429 and I think this line is not ran when passing the file contents in as string.
If the sass2scss function was exposed, I could convert the code myself on my importer code.
