Add labeling opportunity to <Filter> component

[balanza]

Description

The <Filter> component now allows options as key/value pairs. This is to cope with cases in which the value of the element must be different than the one shown.
Also, it enables a single value to be selected using a simple string, being more permissive on the allowed input.

This PR introduces no breaking changes.

Usage

// normal usage
<Filter 
     value={["Mario Rossi"]}
     options={["Mario Rossi", "Giuseppe Verdi"]} />

// using string as value
<Filter 
     value="Mario Rossi"
     options={["Mario Rossi", "Giuseppe Verdi"]} />

// with key/value
<Filter 
     value={["mario_rossi"}
     options={[
       ["mario_rossi", "Mario Rossi"], 
       ["giuseppe_verdi", "Giuseppe Verdi"]
     ]} />
