Add handling of numeric values for scraping nutritional information

[mblennegard]

• Adds handling of numeric values when scraping nutritional information.
• Adds helper function to make sure the units are always imported in the same way, e.g. always g and mg, instead of what might exist on the website (grams, milligrams etc.).

Adds multiple additional test cases to schema-recipe_test.go:

• nutrional info without space characters (renamed the old test case, "simple string")
• nutrional info with abbreviated suffixes
• nutrional info with non-abbreviated singular suffixes
• nutrional info with non-abbreviated plural suffixes
• nutrional info without suffixes as strings
• nutrional info without suffixes as integers

Excellent work, thank you so much! I'll fix the conflicting files later today to then merge it.

Thank you, glad I could help...even though it turned out to be a bit of a rabbit hole. 😋
But besides adding scraping of number values which was the original change, it should now be decently prepared for that potential change to INTEGERS in the database table in the future, so that feels quite satisfying. 😎

Let me know if you want me to look at something else or even assign me some issues.
I have struggled with storing recipes for the past 15 years but feel that Recipya is shaping up to solve everything I need. And not to mention that you have been very active with adding features and fixes which is great to see. 🙏
