DRAFT: try to remove code duplication for different datatypes using macro

[evgenii-kuznetcov]

Didn't want to open macro pandora box but this makes code much shorter. IDE support in vscode still works.
If we like the approach, I can add missing datatypes

It does make the code shorter, but actually, I find the tdigest_cast version more elegant. We have to cast anyways, so we can also do that beforehand. There's no performance impact from that. What do you think?

Agree, tdigest_cast should be better. Didn't notice this function and it was not used

[thobai]

ok, then we should make that one the default and actually remove the other one. But for that we also have to bring in the changes that you already did for the current function. Will you take this over or shall I do it sometime?
