Improvements

supabase.auth namespace added which includes:

• supabase.auth.signup(email, password)
• supabase.auth.login(email, password)
• supabase.auth.logout()
• supabase.auth.refreshToken()
• supabase.auth.user()

Breaking changes

• will not work with "pre-auth" Supabase backends. If you're seeing Error: {“message”:“Server lacks JWT secret”} you will need to use version v0.34.0 or lower
