test_decoder.py and test_encoder.py test cases have invalid default values

[bkeryan]

Bug Report

Some of the test_decoder.py and test_encoder.py test cases fail if we change ParameterMetadata.initialize to always validate the default value type.

Repro or Code Sample

In ParameterMetadata.initialize, change

        if validate_type:
            _validate_default_value_type(parameter_metadata)

to

        _validate_default_value_type(parameter_metadata)

Expected Behavior

Tests still pass.

Current Behavior

Float/double array tests fail because they contain ints, also see #824

DoubleXYData tests fail too:

@dixonjoel Is DoubleXYData supported for configurations? Or only outputs?

Possible Solution

Float/double: see #824

DoubleXYData: not sure.

Context

This came up during the code review for #807

@bkeryan We haven't made any effort to support DoubleXYData for inputs so I'm not surprised this fails.
