rewrite fingerprint storage to no longer need 64-bit members
...
so that it can be stored using standard alignment requirement (sizeof(void*)).
Distance function still requires 64-bit signed multiplication though,
so it won't change the issue regarding the bug in ubsan for clang 32-bit on github ci.

added a faster block splitter variant
...
that samples 1 in 5 positions.
This variant is fast enough for lazy2 and btlazy2,
but it's less good in combination with post-splitter at higher levels (>= btopt).
