Check if given value is a valid UIC location code.

# is-uic-location-code

Check if given value is a valid [UIC location code (ENEE)](https://uic.org/location-codes-enee). Uses the [`uic-codes`](https://github.com/derhuerst/uic-codes) package. Note that only 7-character codes are considered valid for now (instead of 8-digit with checksum, as specified by UIC), because most operators don't provide it, so that 8-digit codes are more likely the result of bugs or inconsistencies.
