Update UserPlexTV.AdsConsent* types

[dimitarvdimitrov]

plex.tv is returning different types for

• adsConsent (used to be string, now bool)
• adsConsentSetAt (used to be string, now int)
• adsConsentReminderAt (used to be string, now int).

This breaks SignIn and Plex.MyAccount.

An example response is

{
  "adsConsent":true,
  "adsConsentSetAt":1613945192,
  "adsConsentReminderAt":1645481192
}
