Switch scheduled hot zone check to search instead of split (#1313)

Browse Source 
Using search_deliminated_string here is significantly faster than
splitting, most likely because of dynamic memory management

Some tests on my system:

----------------------------------------------------
Benchmark             Time           CPU Iterations
----------------------------------------------------
bench_split         864 ns        864 ns     807922
bench_search         35 ns         35 ns   20265205

This test was a case where the string was present somewhere in the
middle which gave a ~96% speed up

----------------------------------------------------
Benchmark             Time           CPU Iterations
----------------------------------------------------
bench_split         936 ns        936 ns     725518
bench_search         61 ns         61 ns   11156359

This test was when the string was not present, which will be the vast
majority of times this is actually checked, was ~93% speed up
