Make parsing Data.Text.Text slightly nicer
Make parsing Data.Text.Text slightly nicer

Parsec has had support for parsing Text Since version 3.1.2, so we don't need
`T.unpack text` as long as we also import `Text.Parsec.Text`.

This also means that the code only requires `(Text, pack)` from `Data.Text`, so
import only those (unqualified).
