This will do nothing to naturally serializable types (bool, int, float)

This will convert Decimal values to their tuple encodings.
See: https://docs.python.org/3.9/library/decimal.html#decimal.Decimal.as_tuple
The custom encoding follows the template:
{
NUMERIC_KEY: <type-as-a-string>,
NUMERIC_VALUE_KEY: <value>

The values for the NUMERIC_KEY and NUMERIC_VALUE_KEY constants are attributes
to the `snappiershot.serializers.constants.CustomEncodedNumericTypes` class.
