Rules with no Spaces in numerals

Hi,

the rule below works for Italian in parsing number with three digits such as `tre cento venti` (320), but fails in recognizing the same expression without spaces (`trecentoventi`) which is actually the correct one in Italian.

Could anyone points out an easy way to transform this rule, to make it working without spaces?

Thanks! 🙏

```haskell
ruleNumerals :: Rule
ruleNumerals = Rule
{ name = "numbers 200..999"
, pattern =
[ numberBetween 2 10
, numberWith TNumeral.value (== 100)
, numberBetween 0 100
]
, prod = \tokens -> case tokens of
(Token Numeral NumeralData{TNumeral.value = v1}:
Token Numeral NumeralData{TNumeral.value = v2}:
Token Numeral NumeralData{TNumeral.value = v3}:
_) -> double $ v1 * v2 + v3
_ -> Nothing
}
```
