Comment:
I added one more package here, which also depends on cysignals. This is the only one I had to `make_check=no` because it is a pain to check before installing, but it's mostly a trivial wrapper package for `primecount`. A simple after-installation test:
```
$ time python -c 'import primecountpy; print(primecountpy.prime_pi(10**18))'
24739954287740860

real    0m3.885s
user    4m0.882s
sys     0m0.829s
```
If one needs to go farther, use `prime_pi_128`:
```
$ time python -c 'import primecountpy; print(primecountpy.prime_pi_128(10**19))'
234057667276344607

real    0m16.092s
user    18m0.676s
sys     0m1.086s
$ time python -c 'import primecountpy; print(primecountpy.prime_pi_128(10**20))'
2220819602560918840

real    1m3.085s
user    73m49.885s
sys     0m1.908s
```
Should be O(n<sup>2/3</sup>) and take good advantage of threads.
