Add support: Puyo Puyo / Dr. Robotnik's Mean Bean Machine

[radioshadow]

First, I made a request about this here: #75

I don't know how to delete it. Feel free to do so.

It would be great if we could add support "Puyo Puyo / Dr. Robotnik's Mean Bean Machine". The good news is that it uses the Sonic 2 format, but there are some differences:

1. Each pointer to each frame is a long value instead of a word value.
2. Same as Sonic 2 sprite attribute, but stores the Link ID value.
3. Before the spritePiece data is a word value that stores how many sprites that frame uses.

1 - This shouldn't be too hard to change to support.

2 - It would only need to remember the Link ID from the asm file.

3 - Flex2 I presume should be able to know the number of sprites for each frame.

I recently made a tool that can extract the sprite mapping data from Puyo/MBM into Sonic 2's layout. With this in mind, I have put a sample of the Arms Intro files:

• ASM file with the sprite attributes.
• Uncompressed art tiles.
• Palette file.

Arms Intro - Sprite Mappings.zip

This would greatly help out with the following projects:
