Breaking changes

Decompression frame check is strictly

Previous version use ZSTD_getDecompressedSize when check decompression string, but this method is obsolete.
So, v1.5.2.3 zstd-ruby gem uses ZSTD_getFrameContentSize .
https://raw.githack.com/facebook/zstd/release/doc/zstd_manual.html#Chapter3

In ZSTD_getFrameContentSize, an empty string with decompression is invalid, so in the spec, an empty string decompression should have been treated as an error.

Release v1.5.2.2

Bug fix release.
Fixed SEGV when GC occurs during streaming compress and decompress.

Release v1.5.2.1

Support Streaming Compression and Decompression!
