0.8.0

• Updated for Streamly 0.10.0.
• Added proper concurrency support, including safety upon asynchronous exceptions. (The previous versions were unreliable in concurrent settings—segfaults, deadlocks, etc.)
• A byproduct of the previous point: writeLMDB no longer maintains its own read-write transactions under the hood.
• Added the ability to chunk the read-only transactions (by bytes or number of pairs) that readLMDB can create under the hood.
• Added the ability to use read-write transactions for readLMDB.
• Eliminated the Void seed for readLMDB.
• Added more choices for readStart.
• Added the ability to stream unexpected key-value pairs in writeLMDB into a separate fold.
• Added getLMDB for getting a single key-value pair normally (without streaming).
• Added writeLMDBChunk for writing key-value pairs normally (without streaming).
• Added chunkPairs/chunkPairsFold convenience functions that allow chunking a stream of key-value pairs (by bytes or number of pairs).
• Added deleteLMDB for deleting key-value pairs.
• Made the unsafe FFI functionality internal.
• Improved documentation, esp. regarding caveats for long-lived transactions and various lower-level LMDB requirements.
