add operator to convert frozen::string to std::string view (with c++17 and more)

[gvollant]

With this operator, it is more easy to convert

const std::unordered_map<std::string_view, std::string_view> network_map({

to

frozen::unordered_map<frozen::string, frozen::string, 1047>network_map = {

you could use other.compare here

LGTM, with the minor extra nit in comment. Could you just add a test case that involves these two additions? thanks.

@Neustradamus write on gvollant/smartversion#1

@serge-sans-paille I rewrote it to use the std::string_view internal compare code (which use often SIMD optimisation)

@gvollant looks good! can you just add a test case and we're done :-)
