ghc::filesystem under C++17 of C++20.
Starting with v1.5.2 `ghc::filesystem` will try to allow the use of
`std::experimental::basic_string_view` where it detects is availability.
Additionally if you have a `basic_string_view` compatible c++11
implementation it can be used instead of `std::basic_string_view`
by defining `GHC_HAS_CUSTOM_STRING_VIEW` and importing the
implementation into the `ghc::filesystem` namespace with:
```cpp
namespace ghc {
namespace filesystem {
using my::basic_string_view;
}

## Release Notes
### v1.5.1 (WIP)
### [v1.5.2](https://github.com/gulrak/filesystem/releases/tag/v1.5.2)
* Enhancement [#104](https://github.com/gulrak/filesystem/issues/104),
on POSIX backend: optimized reuse of status information and reduced
`directory_entry` creation leads to about 20%-25% in tests with
`recursive_directory_iterator` over a larger directory tree.
* Pull request [#103](https://github.com/gulrak/filesystem/pull/103), `wchar_t`
was not in the list of supported char types on non-Windows backends.
* Pull request [#102](https://github.com/gulrak/filesystem/pull/102), improved
`string_view` support makes use of `<string_view>` or `<experiemental/string_view>`
when available, and allows use of custom `basic_string_view` implementation
when defining `GHC_HAS_CUSTOM_STRING_VIEW` and importing the string view
into the `ghc::filesystem` namespace before including filesystem header.
* Pull request [#101](https://github.com/gulrak/filesystem/pull/101), fix for
[#100](https://github.com/gulrak/filesystem/issues/100), append and concat
type of operations on path called redundant conversions.
