Internal font list on Windows still uses "\" path sep

Thank you so much for fixing #20. Internal font loading works correctly when using "/" path separator (i.e. "c64/platoon2"), however the internal font list still returns paths with the windows path separator (\).

Configuration

OS type and version: Windows 10 21H1 JVM type and version: 11.0.13 Scala version: 2.12.13 Figlet4s version: 0.3.1

Problem

Needless to say, using C64 fonts from the internal lists as-is fails:

  val text = "hello, world!"
  val font = Figlet4s.internalFonts.find(_.startsWith("c64")).get
  println(font)
  val banner = Figlet4s.builder(text).withInternalFont(font).render().asString()

This fails witth:

Notes

As I wrote in #20, resources always use / path separator, regardless of the OS path separators, thus treating resource paths as Path object is little erroneous. At the very list you'll want to do something like this in the end: .replaceAll(File.pathSeparator, "/").
