Update snap offline tests (#1199)
* Re-implemented `hexaryFollow()` in a more general fashion

details:
+ New name for re-implemented `hexaryFollow()` is `hexaryPath()`
+ Renamed `rTreeFollow()` as `hexaryPath()`

why:
  Returning similarly organised structures, the results of the
  `hexaryPath()` functions become comparable when running over
  the persistent and the in-memory databases.

* Added traversal functionality for persistent ChainDB

* Using `Account` values as re-packed Blob

* Repack samples as compressed data files

* Produce test data

details:
+ Can force pivot state root switch after minimal coverage.
+ For emulating certain network behaviour, downloading accounts stops for
  a particular pivot state root if 30% (some static number) coverage is
  reached. Following accounts are downloaded for a later pivot state root.

Snap accounts bulk import preparer (#1183)
* Provided common scheduler API, applied to `full` sync

* Use hexary trie as storage for proofs_db records

also:
 + Store metadata with account for keeping track of account state
 + add iterator over accounts

* Common scheduler API applied to `snap` sync

* Prepare for accounts bulk import

details:
+ Added some ad-hoc checks for proving accounts data received from the
  snap/1 (will be replaced by proper database version when ready)
+ Added code that dumps some of the received snap/1 data into a file
  (turned of by default, see `worker_desc.nim`)

Store proved snap accounts (#1145)
* Relocated `IntervalSets` to nim-stew repo

* Accumulate accounts on temporary kv-DB

why:
  Explore the data as returned from snap/1. Will be converted to a
  `eth/db` next.

details:
  Verify and accumulate per/state-root accounts downloaded via snap.

also:
  Some unit tests

* Replace `Table` by `TrieDatabaseRef` for accounts accumulator

* update ticker statistics

details:
  mean/variance based counter update

* allow persistent db for proved accounts

* rebase, and globally activate unit test

* fix statistics
