* latisbooks: fix page parsing
Likely from a preprocessor change on the site's end, the element
containing the images had changed.
* latisbooks: fix cover art
The cover art being used for the comic is pulled from the "latest page"
preview on the archive page, which is a square image that tends to not
represent the comic very well. Additionally, recently it has failed to
load properly for whatever reason. As a remedy, I chose page 198 to be
the proper cover. I chose it as it is an interstitial cover page
featuring the main character, with no text or elements that tie it to a
specific arc.
* latisbooks: version bump
my bad, I thought it worked without the extra strings, but I guess when
I tested it, the chapter cache was stale. Even with debugging tools,
Android is pain.
Not all pages have accompanying text, but it's nice to be able to see
the text when there is some. Examples are `No Comic (03/14/22)` and
`Meidri (Interspecies Reviewers)`
This is done in a nearly identical way to the xkcd source's alt-text
pages, with nearly identical code.
Also handle the extremely rare case where there are multiple images for
the same page. The only instance I can recall is `Page 23+24`
