feat: allow basic win32 backslash use

Even though backslashes are not supposed to be used with globs,
glob-parent still did its job of separating out the glob-like
sections prior to escaping functionality being added. This restores
that capability for basic cases. Users will not be able to use
backslashes as their path separator AND escape characters; if
escapes are needed they are responsible for providing their globs
with the appropriate forward-slash separators.
