Filter / pass errors to client-side

[brillout]

By default, for security reasons, Telefunc doesn't pass errors to the client-side.

But this isn't convenient, a good compromise could be:

import { config } form 'telefunc'

config.passErrorToClient = (error) => {
   // Pass error if it has a 4xx status code (some validation libraries automatically generate a status code)
   return error.statusCode.startsWith('4')

   // Completely opt out
   return true
}
