Updated run_prompt to handle multiline statements

[spralja]

Previously multiline statements were not possible because the scanner automatically appends the EOF token

Originally I thought fixing this might involve complicate syntax checking like makin sure that all '(' are
closed etc.

I think this solution is the simplest to implement, that is that: every statement is ended with a empty input
(newline).

I think its fine for now just not a nice user experience to press enter 2 times... An alternative might be to allow a specific keybinding (shift+enter) to insert a newline to stdin and stdout. Otherwise we can also implement something along these lines

while line.endsWith('{'):
   ...

This way it adds a newline when needed not everytime.

yes but what about

1 ==
1
;

There is just to many edge cases

[spralja]

but shift enter thing sounds nice

Idk I feel like that should be an error lol, or maybe we make it so it waits until ;?

if(value) {
}

It seems that detecting shift+enter is not the easiest because it's platform dependent, with there being difficulty covering major systems (I'm personally using Ubuntu WSL and the most commonly used library doesn't support it)
