Add py-parse-type 0.5.6

parse_type extends the parse module (opposite of string.format()) with the
following features:

• build type converters for common use cases (enum/mapping, choice)
• build a type converter with a cardinality constraint (0..1, 0..*, 1..*) from the type converter with cardinality=1.
• compose a type converter from other type converters
• an extended parser that supports the CardinalityField naming schema and creates missing type variants (0..1, 0..*, 1..*) from the primary type converter
