TOML-specific combinators for converting between TOML and Haskell primitive
types, e.g. 'Int', 'ByteString'.

For the overall picture you can see how different types are represented by
codecs in the following table:

+---------------------------+-----------------+---------------------------+

+---------------------------+-----------------+---------------------------+
| 'Integer'                 | @a = 100@       | 'integer' "a"             |
+---------------------------+-----------------+---------------------------+
| 'Int'                     | @a = -42@       | 'int' "a"                 |
+---------------------------+-----------------+---------------------------+
| 'Natural'                 | @a = 11@        | 'natural' "a"             |
+---------------------------+-----------------+---------------------------+
| 'Word'                    | @a = 1@         | 'word' "a"                |
+---------------------------+-----------------+---------------------------+
| 'Word8'                   | @a = 1@         | 'word8' "a"               |
+---------------------------+-----------------+---------------------------+
| 'Double'                  | @a = 36.6@      | 'double' "a"              |
+---------------------------+-----------------+---------------------------+
| 'Float'                   | @a = -100.09@   | 'float' "a"               |
+---------------------------+-----------------+---------------------------+
| 'String'                  | @a = \"Hello\"@ | 'string' "a"              |

+---------------------------+-----------------+---------------------------+
| 'ByteString'              | @a = \"Hello\"@ | 'byteString' "a"          |
+---------------------------+-----------------+---------------------------+
| Lazy'BL.ByteString'       | @a = \"Hey\"@   | 'lazyByteString' "a"      |
+---------------------------+-----------------+---------------------------+
| 'ByteString' as Array     | @a = [10, 15]@  | 'byteStringArray' "a"     |
+---------------------------+-----------------+---------------------------+
