* Fix for [#203](https://github.com/gulrak/filesystem/issues/203), directory
iteration and `proximate()` are available in builds without exception

* Fix for [#185](https://github.com/gulrak/filesystem/issues/185),
`lexically_normal()` now preserves unresolved parent components in relative

* Pull requests [#198](https://github.com/gulrak/filesystem/pull/198) and
[#199](https://github.com/gulrak/filesystem/pull/199), updated CI for current
runners and compiler toolchains, retaining legacy compiler and MSVC v142
