note that this function could be work in progress and would not always perform as well as demonstrated on any samples. the lossless compression level over this transformation can be increased to get smaller filesize by using -sN:

N: from 0 to 9 — 0: fast and good compression — 9: slow, but better compression
pingo flags -sN target
