Modified Better String Library

This is an inspired version of Paul Hsieh's Better String Library, Better String Library, sds

bstr is a string library for c designated to augmenting the limited libc string handling. Strings are handled similarly to rust where a fat pointer is used to hold the string and slices can be passed around to operate/inspect a string buffer. The only form of allocation in this library is with bstr so any bstr declared has to be ended with a bstrFree().

A c style string/bstr can be converted to a slice. A slice is a base pointer + len. This works similar to a std::span.
