Do not reuse ZstdFrameDecompressor in ZstdDecompressor #139

ZstdFrameDecompressor is not thread safe.

That's intentional. ZstdDecompressor is not thread safe, but instances can be used multiple times. ZstdFrameDecompressor has internal buffers that should be reused to avoid unnecessary allocations when ZstdDecompressor.decompress() gets called multiple times.
