Read(Span) and Write(byte[], int, int) check whether the blob was disposed, but Write(ReadOnlySpan) didn't. Writing to a disposed blob through the span overload passed the null handle to sqlite3_blob_write and failed with "ArgumentNullException: SafeHandle cannot be null", and an empty write silently succeeded.

Add the same disposed check to the span overload.
