[Lensdump] New pattern for direct file URLs

[taskhawk]

Lensdump just changed their direct file URL format and the new redirected URLs are not being matched by the Lensdump image extractor pattern, instead being processed as a generic direct link.

Example:

Old URL: https://d.l3n.co/i/PI10se.jpg
New URL: https://d.l3n.co/PI10se.jpg

Basically they just removed the i/ segment.

$ gallery-dl -K "https://d.l3n.co/PI10se.jpg" 
Keywords for directory names:
