refactor!: remove text/* files, which are no longer useful

With the addition of more defect bits, most QA bins have some sort of
defect, especially RG-A Pass 2, where every single QA bin has the
`BSAWrong` bit set. These text files therefore have little to no value,
so this PR removes them as well as the generation script. The underlying
scripts will remain, however, in case they are needed in the future.
