transit RoaringBitmap and techml-dataset namespace copy

[awb99]

techml-dataset now brings the namespace tech.v3.libs.clj-transit. tmdjs still contains tech.v3.libs.transit namespace which I believe is fundamentally the same as the one that is now in techml-dataset. Perhaps tmlds should remove this namespace?

The roaring bitmap issue is applying also here: https://github.com/techascent/tech.ml.dataset/issues/425
