adds range to compactable file (#3883)
Now that tablet files have an associated range, this information should
be made available to compaction plugins. Making this information
available to plugins enable uses cases like selecting files with ranges
for compaction. This commit makes that information avialable by adding a
getRange method to CompactableFile
