Add support for non-English language data files

[nugget]

The top section of each Road Trip CSV data file contains a block that advertises the file's version, language, and CSV delimeter values. This package has only been tested on english language data files.

Since we rely on section header names in the data file to distinguish data blocks it's feasible that these header strings change if you're running Road Trip in a different base language.

Example file header:

ROAD TRIP CSV ",."
Version,Language
1500,en
