Raw hazelnuts and walnuts are unrealistically disgusting

[KITbutler]

Describe the bug
When shelled but not roasted walnuts and hazelnuts give a hefty -10 fun, on par with unprepared raw meat and 2.5x as bad as drinking pure vinegar!

To Reproduce
See /data/json/items/comestibles/nuts.json or spawn any of the mentioned (shelled) nuts in-game.

Expected behavior
In fact both hazelnuts and walnuts are perfectly palatable raw (allergies notwithstanding) and especially the latter see plenty of use in muesli, salads, cheese or as simple snacks fresh from their shells. I cannot personally vouch for hickory nuts but based on a quick search "shagbark" nuts allegedly are rather tasty as well. Chestnuts should be mildly unpleasant at worst.

Walnuts, hazelnuts and (shagbark) hickory should give +1 in line with other "tasty" nuts, chestnuts between -1 and +1. Acorns might be a little too severe as well but definitely deserve -10 or worse for being excessively bitter (and toxic in large quantities).

Agreed, while shelled walnuts are a tad abrasive, they absolutely do not need cooking to be palatable - or tasty.

P.S. If your walnuts are bitter, 1: they're unripe and 2: the thin peel is the bitter part and can be, with some difficulty, removed.
