Dutch/Estonian: dash is not always a separator

[aleene]

Describe the bug

The dash should not always been interpreted as a separator. In dutch it is a way to limit repetitions.

Other examples:

• mono- en diglyceriden van vetzuren veresterd met mono- en diacetylwijnsteenzuur

To Reproduce

See: https://nl.openfoodfacts.org/product/8718907369589/bloemenhoning-albert-heijn

Expected behavior

For instance: EU- en niet-EU-honing, should not be expanded to EU, niet-EU-honing, but should left untouched. In dutch this is interpreted as EU-honing, niet-EU-honing.

Additional context

A parse rule could be based on the surroundings of the dash:

• dash must come directly after a caharacter;
• dash is followed by a space and then the characters en;
• (more to follow)

Number of products impacted

Happens quite often.

It's strange, if I remove the extra space in "gemengde EU - en niet-EU-honing" (before the first EU), it's added back.

Another example:

• gerehydrateerd SOJA- en TARWE-EIWIT: is broken in two

In Estonian the same language construction is used:

• lõhna- ja maitseaine

Another interesting product: https://nl.openfoodfacts.org/product/8712800025665/brownie-mona .
in this case an ingredient is not parsed at all.

Oups sorry I inadvertently removed ingredients on above product, but restore them thereafter !
