Authentication Token Persistence

[UltraWelfare]

As far as I understand the token is stored in memory

https://github.com/sebdesign/laravel-viva-payments/blob/52796a904fac5783409f876093cdf27b8a99bd99/src/Client.php#L221-L230

Which means that if, for ex; N users do a Viva::orders()->create call -> N authentication calls to Viva would happen. Each request would use a different token.

Shouldn't the authentication call be done once, then refresh when it expires? Probably store it using cache or something equivalent.
