rm .nst, any_quick -> any

If we load with dumb_read_any_quick, seeking is broken in DUMB 2.0 but
works in 2.0.0~20 (20 commits ago behind 2.0.0). If we load with
dumb_read_any, it works in both DUMB 2.0 and 2.0.0~20.

I have no clue why this is, and I will investigate. I assume it's from
our bad 64-bit conversion of the DUMB API that silently broke inside DUMB.
