so it's not super better but at least it's not worse, and I think in real world it will be better.

it looks better than LMDB, but I think it's worse in the real world because it uses too much memory and have
all the ristretto cache overhead that looks like it goes not very well with the golang gc, who knows.

(insert doesn't complete)

by the way these benchmarks are all wrong because they keep halting the computer for some reason. these DBs may not be well-suited for the incessant calling that the go benchmark framework does, I don't know. arbitrarily reducing the number of iterations almost made them work, but tweaking that value yields very different results so everything is useless.

v0.8.0

delete bolt.

aside from other bugs that have happened before, this one:

https://cdn.satellite.earth/25a4bc5c9fd7617cdcba309a552d227283fb2d36aa75f47b12c0b83510c4de88.png

is caused directly by bbolt's `unsafe` usage.

something wrong is not right inside bbolt's codebase and I don't think it's worth trying to solve it.

bolt is kinda annoying anyway, like it blocks the database and makes things hang forever, has some
weird locking and stuff. so if people want a pure-go setup they can use badger, and if they want better
read performance they should use LMDB. bolt is unnecessary.

v0.7.2

add wrappers/count

v0.7.1
