ENH: Build bundle list dynamically depending on atlas version

Build bundle list dynamically depending on atlas version.

Add the accompanying files:
- The atlas bundle data (bundle label, short and long names) as CSV
  files.
- The utilities functions required to read the bundle data.
- Provide some level of encapsulation when adding the methods.

Add a utility script to query the bundles corresponding to the files in
an atlas available in a local disk.

Add the corresponding tests.
