Add Grow and Deflate mods

[Rian8337]

This adds the Grow and Deflate mods, which expands/shrinks hit objects during their fade in animation.

Due to similarity in gameplay behavior, I decided to group them into one PR. Of note, the maximum initial scale of Deflate is set to 10 as circle sizes are already big enough.

Current blockers:

• Slider body looks odd (too fat or too slim) when scaled
• Hit judgement area does not account for current scale (needs verification)
