Function declarations/expressions with # names not properly handled

[Conduitry]

cr.print(cr.b`function #foo() { }`).code // => 'function #foo() {\n\t\n}'

If this were handled correctly, it would allow a nice solution to sveltejs/svelte#3900

The only situation in which this really needs deconflicting is when there's code inside the function trying to access a variable foo declared outside the function. I don't know how this library handles this though, so it might just be easier to deconflict function #foo() { } as though it were a regular variable declaration.

Actually, no, we can only cut corners when it's a named function expression, not a function declaration. It seems easiest to just always deconflict this.

This looks like it works. PR coming soon.
