cynic be8546bdf5 make 'oracles' feature backwards compatible with php 7.4 (#13)
adds implementations of `str_contains` and `str_starts_with` that are used if the functions are not already defined. this should enable 4get to work on both php 7.4 and php 8.*

my instance is currently on 7.4.33, and you can see the oracles working here:
[calc.php](https://4get.silly.computer/web?s=2%2B4*(2^2))
[encoder.php](https://4get.silly.computer/web?s=md5+hamburger)
[numerics.php](https://4get.silly.computer/web?s=0xf0f0f)
[time.php](https://4get.silly.computer/web?s=what+is+the+time+right+now+tz%253Aest)
