Jpeg magic number detection with SAUCE metadata

https://defacto2.net/f/aa2ebd3

SAUCE metadata with comments conflict with the magic number JPEG image detection.
This is due to JPEGs also having its metadata at the end of the file. A possible fix,

1. whenever SAUCE metadata is detected
2. do deep reverse scan of the data
3. until the end of the CMNT tag is found, ff d9 1a C O M N T

It might be possible to display a sequence of vertical screens, instead of clearing the current screen, adjust the ansi cursor position to create new page, below the existing art.

ANSI blinking support

Not commonly used, but is found enough in 1980s and early 1990 ANSI art. Has a dramatic, animation effect with some art. However, blinking in CSS requires a lot of boiler plate code for each individual colour.
