Preprocessor not parsing values correctly

[JCoetzee123]

Title

Preprocessor not parsing values correctly

Steps to reproduce

1. Import the SPiRA framework

import spira.all as spira

2. Create a class accepting spira.ParameterInitializer and initialize simple integer parameter

class Layer(spira.ParameterInitializer):
    integer = spira.IntegerParameter(default="1.2", preprocess=spira.ProcessorInt())

3. Instantiate a layer class to be called in your main script

layer =  Layer()
print(layer.integer)

4. Execute the script in bash

Expected Behavior (correct)

Paramater should print out as a rounded integer (~1)

Current Behavior (incorrect)

Traceback (most recent call last):
