SmallString is a very simple utf8 string class. It's purpose is performance.
It uses a short string opimization which provides 31 bytes of heap free
memory to save a 30 bytes long string plus null terminator. If the string
gets larger heap is allocated. The grow strategy is 1.5 to improve reuse
of allocated memory.
It uses optionally constexpr to provide string literals.
