Konstantin Knizhnik 88b13d4552 implement rolling hyper-log-log algorithm (#8068 )

## Problem

See #7466

## Summary of changes

Implement algorithm descried in
https://hal.science/hal-00465313/document

Now new GUC is added:
`neon.wss_max_duration` which specifies size of sliding window (in
seconds). Default value is 1 hour.

It is possible to request estimation of working set sizes (within this
window using new function
`approximate_working_set_size_seconds`. Old function
`approximate_working_set_size` is preserved for backward compatibility.
But its scope is also limited by `neon.wss_max_duration`.

Version of Neon extension is changed to 1.4
