IT: support Decimal class

[bryananderson]

Changes proposed in this pull request:

• Italian language: detect non-integer cardinals regardless of whether they are float or Decimal (they will be the latter if a string is passed to num2words() rather than a float)
• Add test for this case

Status

• READY
• HOLD
• WIP (Work-In-Progress)

How to verify this change

Run tests

[bryananderson]

I fixed the test/flake8 failures locally. One issue was that my change now causes 1.0 to return "uno" unstead of "uno virgola zero". However, I believe this is actually the desired behavior based on checking several other languages:

>>> num2words(1.0, lang='it')
'uno virgola zero'
>>> num2words(1.0, lang='fr')
'un'
>>> num2words(1.0, lang='de')
'eins'
>>> num2words(1.0, lang='es')
'uno'
>>> num2words(1.0, lang='en')
'one'
>>> num2words(1.0, lang='pt')
'um'
