feat: converter accepts the constructs of goodluke and SaintlyCorruption

`init -490 screen`, `import x as y` and `from m import A as B`, classes with @renpy.pure, pickle hooks
on classes, `*` items in tuples and lists, generator functions (yield statements; the player runs them
to the end), multi-line expressions that need brackets, Null() and Animation() images, images given as
expressions (`"path/{}.png".format(x)`, f-strings), window statements in init, `offset` in ATL, input
widgets with their values and the focus/confirm actions, `continue` and `break` in screens, `drag`
and DiamondBox-style `fixed` with cell_size, `getattr(...)()` calls, transforms called with arguments,
and the whitelist for the new runtime. JSON files of a game are shipped as data files. Also fixes
blocking_names failing on a call of a call during full conversion.
