inout does not work with basic types

[0xxon]

According to the documentation at https://docs.zeek.org/projects/spicy/en/latest/programming/parsing.html?highlight=inout#unit-parameters, a string parameter should be able to be declared as inout.

Trying this:

module TESTING;
public type Handshake = unit(inout version: string) {
  handshakes: bytes &size=0;
};

Yields the following error message:

[error] test3.spicy:3:1-5:3: only parameters of reference type can be 'inout' for struct parameters

Expected behavior: no error and parameter is modifiable in the unit.

This actually works today, but one needs to write additional code to pass basic types as unit parameters. I created #755 to document this.

I think this is fixed - the example works now.

Thanks for checking in on this @0xxon. This was fixed by #1170 which will be part of v1.6.0.
