Sprites (loaded with lsp) sometimes not cleared (with csp)

[drojf]

Read this for some context on the lsp and csp functions:

• https://07th-mod.github.io/ponscripter-fork/#/?id=lsp-and-csp
• https://07th-mod.github.io/ponscripter-fork/api/#csp
• https://07th-mod.github.io/ponscripter-fork/api/#lsp

I found a case where an animation uses some sprites, but those sprites are never cleared, just moved off-screen. It may be a good idea to scan the script for such cases (lsp without corresponding csp or csp -1.

I don't think this actually causes a crash or any bad behavior in this case, though.

	print 1
