Add renderResultList prop

[ajenkins]

This allows you to replace <FlatList /> with another component. The motivation for this is to allow you to use <Autocomplete /> inside of a <ScrollView /> without getting that VirtualizedLists should never be nested inside plain ScrollViews error.

Fixes #219

I added unit tests, but I also manually tested using my own app. Here's the relevant part of my code so you can see how this would work in practice:

import { useState } from "react";
import { Text, View, Pressable } from "react-native";
import Autocomplete from "react-native-autocomplete-input";

function MyAutocomplete() {
  const [search, setSearch] = useState("");
  const [selectedTag, setSelectedTag] = useState(null);
  const data = [{id: "example", value: "example"}];

  return (
     <Autocomplete
        value={search}
        onChangeText={(text) => {
          setSearch(text);
          setSelectedTag(null);
        }}
        data={[...tags, { id: "new", value: `Create new tag: ${search}` }]}
        renderResultList={({ data, style }) => (
          <View style={style}>
            {data.map(({ id, value }) => (
              <Pressable
                onPress={() => {
                  setSelectedTag(id);
                  if (id !== "new") {
                    setSearch(value);
                  }
                }}
                key={id}
              >
                <Text>{value}</Text>
              </Pressable>
            ))}
          </View>
        )}
        hideResults={search.length < 3}
        containerStyle={{ flexGrow: 1 }}
      />);
}

Thx for contributing! New version is released including the change.

@mrlaessig Doesn't this lose the optimization of a FlatList though? Is there any other solution being worked on that allows us to keep the FlatList under the hood?

[mrlaessig]

FlatList is still the default if no custom list is supplied.

@mrlaessig I understand that but I'm wondering if there is a solution in the works to the VirtualizedList error that isn't at the expense of the FlatList. I'm still getting the error with the latest version and I saw a couple other closed issues about it where some said it was fixed, some said it wasn't. This was the only one where I could see a clear solution but it doesn't seem to be optimal so just seeking clarification, wondering if I missed something. Thanks!
