ddl2cpp command line argument for custom types (#491)

* ddl2cpp command line argument for custom types - Updated the ddl2cpp script to allow custom/extended types through external csv file - Had to re-order the script to allow the command line to be parsed before setting up the parser - Updated README * Test for the command line argument - Script test only for now * Test the custom type argument - Firs a negative test - Last a positive test and compile test against the generated output * Expand the test - Ensure built in types still work - Check capitilisation - Ensure more than one custom works - Check type with spaces --------- Co-authored-by: Carel Combrink <carel.combrink@vastech.co.za>

+
+In case you’re getting notes about unsupported column type consider:
+  - Take a look at the other datatypes in sqlpp11/data_types. They are not hard to implement.
+  - Use the `--datatype-file` command line argument as described below.

 Include generated header (MyTable.h), that’s all.

 If you prefer Ruby over Python, you might want to take a look at https://github.com/douyw/sqlpp11gen

+Unsupported column types:
+-------------
+__Map unsupported column types to supported column types with a csv file__:
+
+One can use the `--datatype-file` command line argument for the ddl2cpp script to map unsupported column types to supported column types.
+
+The format of the csv file is:
+```
+<dataType>, <col_type1>, <col_type2>
+<dataType>, <col_type3>
+```
+
+Where `<dataType>` is one or more of the following internal types:
+
+  - `Boolean`
+  - `Integer`
+  - `Serial`
+  - `FloatingPoint`
+  - `Text`
+  - `Blob`
+  - `Date`
+  - `DateTime`
+  - `Time`
+
+Example:
+
+```
+Boolean, one_or_zero
+Text, url, uuid
+```
