sprites_samus.csv is incomplete

[alex-west]

Current issues:

• The constants column is blank, with a helpful note of "TODO: ADD CONSTANTS"
• The sprite indices should be added to bank_001.asm as appropriate (in the various tables used to set hSpriteId when calling drawSamusSprite)
• The .csv should be hooked up to the build process.
• The function tryPausing excepts the metroid sprite on the HUD to use particular tile indices. The comment column of the .csv should at least contain a warning about this.

Perhaps this would also be a good time to move some of the stuff in the data folder to the samus folder, and other such bits of reorganization.
