* set upper bound on EpochRef cache
* max 32 EpochRef instances
* less memory waste in BlockRef by removing EpochRef seq that is mostly
unused (~20mb)
* less memory waste in dag block lookup by not keeping an extra copy of
digest (~70mb)
* fix `==` and `$` for Eth2Digest
* remove `ChainDAG.tmpState` (~50mb?)
all in all, this branch cuts mainnet memory usage by ~160-180mb and puts
limits on EpochRef cache usage - where normally it hovered around 950mb
before, it's now sitting at 600-700mb on my machine.
* docs
* performance fixes
* don't mark tree cache as dirty on read-only List accesses
* store only blob in memory for keys and signatures, parse blob lazily
* compare public keys by blob instead of parsing / converting to raw
* compare Eth2Digest using non-constant-time comparison
* avoid some unnecessary validator copying
This branch will in particular speed up deposit processing which has
been slowing down block replay.

* Bump BLST
* Test for https://github.com/supranational/blst/issues/22 regression
* Use SHA256 from BLST + bump nim-blscurve to reenable fno-tree-vectorize
* SHA256 on non-blst platforms import fixes
* import fixes again
* can't prefix with nimcrypto
* address review comment [skip ci]
* {.noInit.} on the digests
* ssz: move ref support outside
Instead of allocating ref's inside SSZ, move it to separate helper:
* makes `ref` allocations explicit
* less magic inside SSZ
* `ref` in nim generally means reference whereas SSZ was loading as
value - if a type indeed used references it would get copies instead of
references to a single value on roundtrip which is unexpected
TODO: EF tests would benefit from some refactoring since they all do the
same thing practically..
