default paramater of Float/IntegerParamter can be initialized incorrectly

[JCoetzee123]

Title

default paramater of Float/IntegerParameter can be initialized incorrectly

Steps to reproduce

1. Import the SPiRA framework

import spira.all as spira

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

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

3. Create a Layer class to be called in the script

layer = Layer()

Current behavior (incorrect)

Expected behavior (correct)
