java.util.regex.PatternSyntaxException: Unescaped trailing backslash near index 1

[Rylern]

On Windows, when opening a remote zarr image (e.g. https://uk1s3.embassy.ebi.ac.uk/idr/zarr/v0.4/idr0062A/6001240.zarr), the following exception is thrown:

java.util.regex.PatternSyntaxException: Unescaped trailing backslash near index 1

	at loci.formats.in.ZarrReader.initFile(ZarrReader.java:189)
	at loci.formats.FormatReader.setId(FormatReader.java:1480)

This is due to this line:

ZarrReader/src/loci/formats/services/JZarrServiceImpl.java

Line 84 in 31d6d95

String[] pathSplit = root.toString().split(File.separator);

On Windows, File.separator is \, and calling String.split("\") throws the exception above.

This has also been mentioned in #109, should be fixed with PR #110 .
I'll try again to get PR merged and hopefully can release soon.
