Load external python code

[MikeSmithEU]

Adds --load argument to CLI, allowing to load external code. This allows the toolkit to be more modular and extensible without having to add to the core benchmarkstt code.

Eg.

If you have file test.py in current working directory:

class Uppercase:
    """Uppercase the text"""
    def normalize(self, text):
        return text.upper()

And you do

$> benchmarkstt --load test --help

The help output will have an addition normalizer:

 --uppercase           Uppercase the text

which can be used e.g.

$> echo "Should be uppercased" | benchmarkstt-tools normalization --load test --uppercase
SHOULD BE UPPERCASED
