Update wp-cldr to version 1.2

[sdnunca]

This diff updates the CLDR version to 45.0.0.

Since version 43, timezone data cannot be enumerated from timezone.json.

In order to get the list of English timezones and exemplar cities, this diff extracts the data from cldr-bcp47/bcp47/timezone.json, which has been added to the supplemental folder.

Testing instructions

1. Run ./get-cldr-files.sh
2. Confirm that a new 45.0.0 folder was created in the data folder
3. Run php prune-cldr-files.php to delete unneeded files.
4. Confirm that the size of the 45.0.0 folder is similar to the already existing 41.0.0
5. Run unit tests
6. https://github.com/Automattic/wp-cldr/pull/101 has been created to add the data.

Failed asserting that an array has the key 'America/Los_Angeles'.

Confirm that the size of the 45.0.0 folder is similar to the already existing 41.0.0

@sdnunca My data folder only contains 29.0.0 and 45.0.0

Thanks @d-alleyne, I've rebased the branch, you should now see data version 41.0.0

@d-alleyne thank you, I've updated the script to work with white spaces in the path.
