[Bug] Conda install command in README cannot find merlin-loader package

[beckernick]

Using the README's conda install command in a fresh environment fails with an error indicating the package is not available from any channels. I see there is a merlin-dataloader package in the nvidia channel associated with this repository. Should we be using this instead and update the README command?

@mikemckiernan and @edknv hello. do you mind to test Nick's question above and update the Readme accordingly? Btw, our read me gives this command for conda installation conda install -c nvidia -c rapidsai -c numba -c conda-forge merlin-dataloader python=3.7 cudatoolkit=11.2. I see that it uses Python 3.7. I assume our never lib (nvt, core, ..) versions do not support 3.7. so we need 3.8+, dont we? thanks!
