659717cb1f Allow usage on wasm32-unknown-unknown target (#194) 
* Avoid using time API when we don't need it

This avoids a syscall to the time API when the result is ignored later anyway.

This allows to use the library with default options on wasm32-unknown-unknown, where the unimplemented syscall would panic otherwise.

* eval_send doesn't need to be an Option

We can drop the value manually, thus avoiding unwrap on each access.

* Keep single `use rayon::prelude::*`

If either `rayon` is already imported, then `rayon::prelude::*` should always resolve.

* Extract comparator

* Fully enable non-parallel mode

ff0e3df948 Revert "Make cfzlib the default on platforms that support it" 
This reverts commit 2702145f3f.

cfzlib seems to have a MASSIVE memory leak in it. Trying to use it
when processing many files at once will cause your system to run out
of memory.
