avoid unnecessary data copy when building sample (#204) This method was touched in #203 and I realized that there's really no point copying data into sample_buf, we can just return a pointer to it. Rust handles the lifetimes so we know callers won't do anything fishy with these pointers. Signed-off-by: Andrew Duffy <andrew@a10y.dev>

feat: prune low-value symbols from table on small inputs (#203) When the training corpus is small enough that counts are exact (not sampled), tail-end symbols can cost more table overhead than they save in compression. This adds a pruning step on the final training pass that drops symbols whose savings don't exceed their storage cost (symbol_len + 1 bytes). Only activates when the input is below the sampling threshold (16 KiB), so there is no behavior change for large inputs. But maybe this still helps spiraldb for "weird" users, and generally this pruning is super cheap.
