Make CompressDictLevel part of the public API instead of being internal. This allows users to specify both dictionary and compression level parameters together, which is useful for advanced compression scenarios. Previously CompressDict used level 0 which barely compresses. Based on valyala#63

I'm new to zstd but my understanding is the current CompressDict function compresses with level zero, which barely does anything. This was surprising to me and not what I wanted. This PR just renames compressDictLevel to CompressDictLevel so it is part of the public api
