* Create ArenaScans.kt
Added 'Arena Scans' src override for img selector to mitigate duplicate pages Image selector was returning 2 images for each image (img tag and the noscript img tag). So, added attribute [data-src] which is only available on img under 'readerarea' and not for noscript img. This results in returning one image per img tag.
* Update MangaThemesiaGenerator.kt
