[R] refine record batch factory

[asfimport]

may be useful to handle ...:

• it should be named

• each value can be either an R vector, (converted with array()) or an Array

  So that we can have something like this:

  {code:r}
  record_batch(x = 1:10, y = array(1:10))

1. currently have to go through tibbles
2. record_batch(tibble(x = 1:10, y = 1:10))
   {code}
