Method for one line Guppy entrypoint -> QIR

[trvto]

• For user convienience, add a method that takes a guppy entrypoint function and compiles it directly to QIR bytecode, wrapping guppy.compile
• BONUS POINTS: Add a decorator (something like @guppy_on_h2 for wrapping the guppy entrypoint. It should be a thin wrapper of @guppy.comptime that overrides the compile method and spits out QIR bytecode
