This mapper function converts the single value in a sliding window to LONG.

The mapper.tolong function can be applied to data of type BOOLEAN, STRING, LONG or DOUBLE.

When used on bucketized GTS, this mapper will fail on empty bucket. Use UNBUCKETIZE first.

If the GTS contains duplicated timestamps, this mapper will fail. Use DEDUP first.

mapper.tolong is available since version 1.0.11.
