Added double compression test testing mantissa range which does not fit into signed long.
HEX-1945 fix. TransFVec had bug inflate_impl -> forcibly setting length and sparseLength at the end makes invalid sparseChunks (sparseLen == len, but fewer stored values)..
Fixed error reporting in Reblance task (the map in Reblanace is "inverted" - running on the target chunk instead of source chunk, target chunks is always C0LChunk so no reason to report that, we're really interested in the srcChunk which caused the error)

Also removed mostly broken error reporting in NewChunk.values.
