* use LTO in release builds
This significantly (40%) speeds up block replay and hashing - for example replaying first 1000
blocks, without/with LTO:
```
[arnetheduck@tempus ncli]$ ../env.sh nim c -d:release ncli_db
[arnetheduck@tempus ncli]$ ./ncli_db bench --db:db --network:medalla --slots:1000
Loaded 215006 blocks, head slot 307400

Epoch processing is heavy on both arithmetics and hash caching, both of which get a
significant boost here.
This makes sense: nim creates lots of small functions spread out over many C files. A much
worse solution is to try to annotate code with `inline` - it copies functions to multiple
C files but still doesn't do intermodule optimizations significantly limiting the
compilers' ability to reason about the code, causing bloat and misrepresenting the usefulness
of a function to the call frequency analysis that drives actual (C-compiler) inlining and many
other optimizations.
In particular, many nim functions are part of `system` or the `C` backend - stack tracing,
memory allocation etc - nim's inlining system is pretty incomplete in that it does not deal
with these and many other cases.

add section addressing `address already in use error`. we already sort of cover this in the guide, but i think it makes sense to have it explicitly mentioned here.
* Bump BLST
* Test for https://github.com/supranational/blst/issues/22 regression

* {.noInit.} on the digests
This is one way we could organize the flat file storage for blocks - the
alternative would be to not do `type` in the file itself, but have a
single type per file which arguably is simpler but may become annoying.
Another potential restriction would be to require that blocks are
ordered - with this format, it's a little bit more involved to recreate
an index file, and it's easy to accidentally build in assumptions about
the block order in the main data file.
about 40% better slot processing times (with LTO enabled) - these don't
do BLS but are used
heavily during replay (state transition = slot + block transition)
tests using a recent medalla state and advancing it 1000 slots:

./ncli slots --preState2:state-302271-3c1dbf19-c1f944bf.ssz --slot:1000
--postState2:xx.ssz
