Automatically convert integers to doubles when argument type is double

Describe your changes

This PR allows users to pass an integer to a double argument without Nextflow throwing an error about it being the wrong type.

This fix needs to be ported to Viash 0.9 and dev as well.

Is Short and/or Double also a problem?

[rcannood]

I tried to resolve this by using a more idiomatic casting mechanism, namely:

  // ...
  } else if (par.type == "double") {
    // cast to double if need be
    if (value !instanceof Double) {
      try {
        value = value as Double
      } catch (NumberFormatException e) {
        expectedClass = "Double"
      }
    }
  } // ...

WDYT?

Looks OK. One thing I am wondering about is how hard it would be to refactor the if else structure into a hashmap and a loop.

let's do additional improvements in viash develop, or even in nf-viash ^^
