Restore original sprites (unstitched) from the games

[rozniak]

As brought up in #7 the stitched sprites will have overlapping problems with the isometric view. The original game has the characters (anything more than a single cell tall) split into multiple sprites presumably to solve this overlapping issue.

Unfortunately this means the tedious work done by @TommytheJerk stitching the sprites together is going in the bin. 😩

On the plus side this is far simpler from a ripping perspective as we just use the original data.

Have started this, it's a lot of work...

I have done up to MINIFIG_EAT_L in Junkbot's sprites. I'm pretty sure the bin is separate vertical chunks as well so that needs splitting. I'll rename the other files to their original names based on the DIR/DCR.

I'll actually need to rename MINIFIG_EAT_L to MINIFIG_EAT_R - weirdly the game itself contains two sets for the animation facing left and right... except in both sets Junkbot is facing right. They're exactly the same. Maybe in future we could draw some new sprites to fill in this missing animation.

The next set is MINIFIG_SHIELDEAT_R - there is MINIFIG_SHIELDEAT_L but again it's simply duplicates of the right facing sprites so only need to rip them once.

@TommytheJerk made a good point - not really any reason to draw original sprites for Junkbot eating facing left, it's probably done on purpose to see him facing the 'camera' during those animations.
