Snap sync extractor and sub range proofs cont1 (#1468)
* Redefine `seq[Blob]` => `seq[SnapProof]` for `snap/1` protocol

why:
  Proof nodes are traded as `Blob` type items rather than Nim objects. So
  the RLP transcoder must not extra wrap proofs which are of type
  seq[Blob]. Without custom encoding one would produce a
  `list(blob(item1), blob(item2) ..)` instead of `list(item1, item2 ..)`.

* Limit leaf extractor by RLP size rather than number of items

why:
  To be used serving `snap/1` requests, the result of function
  `hexaryRangeLeafsProof()` is limited by the maximal space
  needed to serialise the result which will be part of the
  `snap/1` repsonse.

* Let the range extractor `hexaryRangeLeafsProof()` return RLP list sizes

why:
  When collecting accounts, the size oft the accounts list when encoded
  as RLP is continually updated. So the summed up value is available
  anyway. For the proof nodes list, there are not many (~ 10) so summing
  up is not expensive here.

Snap sync extractor test sub range proofs (#1460)
* Unit tests to verify calculations based on hard coded constants

why:
  Sizes of RLP encoded objects are available at run time only.

* Changed argument order for `hexaryRangeLeafsProof()` prototype

why:
  Better to read as a stand-alone function (arguments were optimised
  for functional pipelines)

* Run sub-range proof tests for extracted ranges

Snap sync interval range extractor (#1449)
* Update comments and test noise

* Fix boundary proofs

why:
  Where neither used in production, nor unit tested. For production, other
  methods apply to test leaf range integrity directly based of the proof
  nodes.

* Added `hexary_range()`: interval range + proof extractor

details:
+ Will be used for `snap/1` protocol handler
+ Unit tests added (also for testing left boundary proof)

todo:
  Need to verify completeness of proof nodes

* Reduce some nim 1.6 compiler noise

* Stop unit test gossip for ci tests

Declutter snap sync unit tests (#1444)
* Extracted RocksDB timing unit tests into separate file

why:
  make space for more in main module :)

* Extracted `inspectionRunner()` unit tests into separate file

why:
  make space for more in main module :)

* Extracted `storagesRunner()` unit tests into separate file

why:
  make space for more in main module :)

* Extracted pivot checkpoint store/retrieval unit tests into separate file

why:
  make space for more in main module :)

* Extract helper functions into separate source file

* Extracted account import unit tests into separate file

why:
  make space for more in main module :)

* Rename `test_decompose()` => `test_NodeRangeDecompose()`

why:
  There will be more functions with `test_NodeRange` prefix.
