...
These functions could be useful in GPS tracking apps for calculating the summary for height gain/loss
over the given duration `d`.

lib/storage: postpone reading data from blocks during search

This eliminates the need for storing block data into temporary files on a single-node VictoriaMetrics
during heavy queries, which touch big number of time series over long time ranges.
This improves single-node VM performance on heavy queries by up to 2x.
