fix: panic - allow for parameters to be subtype of string

[hlavavit]

Huma panics when query param is slice of string subtypes

for example

results in panic

reflect.Set: value of type []string is not assignable to type []enum.DeviceEvent
goroutine 35 [running]:
net/http.(*conn).serve.func1()

This pullrequest is a fix to that. First time i used golang reflection so feel free to clean it up a bit.

In the code where rabbits play,
New features hop in bright array.
With strings and slices, oh what fun!
Validations shine like the sun.
Let's celebrate this joyful spree,
Hooray for changes, one, two, three! 🐇✨
