feat: Added Contact manager functions

[icleitoncosta]

All the features are functional; however, I couldn't test the synchronization with my phone's calendar because I don't have any devices with that feature enabled.
I leave it here so that anyone with a compatible device can test it.

Todas as funções estão funcionais, porém, eu não pude testar a sincronização com a agenda do meu celular, pois, não tenho nenhum dispositivo que esteja ativo a função.
Deixo a mesma aqui, para quem tenha o dispositivo habilitado, possa-a testar.

Unzip file for test and paste in your browser
wppconnect-wa.zip

await WPP.contact.save('[putNumberHere]@c.us', 'John', { surname: 'Doe', syncAdressBook: true, });

await WPP.contact.remove('[putNumberHere]@c.us');

With given above zip file!

WPP.contact.save is not a function

WPP.contact.save and WPP.contact.remove both are only working for browser, it does not affecting on Mobile device even after refreshing contacts 3 to 4 times

Is the option to sync contacts enabled on your device (iOS or iPhone)? Go to Settings > Privacy > Contacts.
