Returns `void` from the `erase(iterator)` overload

Hi @greg7mdp,

parallel-hashmap/parallel_hashmap/phmap.h

Line 4703 in d676385

// * Returns `void` from the `erase(iterator)` overload.

parallel-hashmap/parallel_hashmap/phmap.h

Line 4768 in d676385

// * Returns `void` from the `erase(iterator)` overload.

Are these typos? I believe it is _erase(iterator) that returns void

Hi @heyfey , you are right, these were typos, I just fixed them (see this commit). Thanks for the report!
