Add function for maps to receive slice of values filtered by given keys about lo HOT 4 CLOSED

I justed added:

• OmitByKeys(map, keysToRemove)
• OmitByValues(map, valuesToRemove)
• OmitBy(map, predicate)
• PickByValues(map, valuesToKeep)
• PickBy(map, predicate)

from lo.

I may suggest PR if needed.

Hi @metalrex100 and thanks for the contribution.

I would rather choose ValuesFilter for a more explicit naming

But I think this helper does too many things.

Why not implementing:

• OmitByKeys(map, keysToRemove)
• OmitByValues(map, valuesToRemove)
• OmitBy(map, predicate)
• PickByKeys(map, keysToKeep)
• PickByValues(map, valuesToKeep)
• PickBy(map, predicate)

Your ValuesF function could be replaced by:

subset := lo.PickByKeys(map[string]int{"foo": 1, "bar": 2, "baz": 3}, []string{"foo", "baz"})
values := lo.Values(subset)

WDYT ?

@samber I thing that PickByKeys is a more clear naming for such functionality, indeed. Will change it.
