* fix missing backslash
* fix: zls escaping colon to %3A on URIs
ZLS escapes a colon char ":" as "%3A" when encoding file paths to URIs
When decoding, need to make the target string 2 character shorter
to compensate for length decrease when replacing %3A with :
* add new failing test because of resize()
* revert changes to %3A handling - problem seems to be with allocator.resize
* switch to realloc
* Fix test failures, revert errdefer->defer
* platform-specific URI tests
URI parsing is highly platform-specific
run Unix-style (file:///home/main.zig) on non-Windows test runners,
run Windows-style (file://c%3A/main.zig) on Windows test runners
