This is a pre-requisite for supporting CLDR v43, where they combine `seeds` locales with `common` locales (https://cldr.unicode.org/index/downloads/cldr-43#h.7s25aqdv767e). In order to have the same coverage level of locales, CLDRConverter tool needs to comb through the locale files based on the `coverageLevels.txt` file, (and the ones we already included as of v42). Confirmed the same set of locales is generated before and after this modification.
