Introduce unique ids

[mieciu]

An attempt to introduce unique object IDs in the ClickHouse realm.

A returned document id (_id field) would have the following syntax:

{hex-encoded timestamp field}qqq{hex-encoded hash of the document}

Of course, the {hex-encoded hash of the document} lives only in Quesma memory:

1. It needs to be re-calculated when returning search hits
2. Quesma need to filter out based on it when rendering hits

Therefore when fetching document with specific _id we could filter out documents with matching timestamp and then filter for that with matching fields, returning the right entry.

This fixes the issue, where JSON view of single document could return a random object from search hits, not necessarily the one clicked.

However (and it's a pretty big however), the "surrounding document" view cannot return the surrounding documents. While the query doesn't error it also doesn't return any documents. The experiment to have that working is carried out is a separate PR, although it's not clear yet if this way of doing things is going to guarantee 100% correctness.
