sorting bcolz ctable

[Eloy Félix]

Hello bcolz group,

I have experience using Pytables before and I was now also checking on bcolz. It seems to have most features that I could need and, if I didn't miss anything, can't say the same for other stuff like PyArrow!

I used to create sorted copies of Pytables tables in order to be able to implement an optimisation in molecular similarity searches when datasets didn't fit into memory.

This is how I did it: https://github.com/chembl/FPSim2/blob/master/FPSim2/io/backends/pytables.py#L144

Is there any way to do the same in bcolz in an "optimised" way?

Kind regards,

Eloy
