Do we have to add TableCollection$sort() method?

Explore this - idea is that we could prep TableCollection without Python.

See https://tskit.dev/tskit/docs/stable/python-api.html#tskit.TableCollection.sort and https://tskit.dev/tskit/docs/stable/python-api.html#tskit.TableCollection.sort_individuals and https://tskit.dev/tskit/docs/stable/python-api.html#tskit.TableCollection.canonicalise

@hannesbecher @LynxJinyangii do you have any thoughts/feedback on this issue - see the current list of TableCollection methods exposed to R in https://github.com/HighlanderLab/RcppTskit/blob/main/RcppTskit/R/Class-TableCollection.R and exposed in C++ in https://github.com/HighlanderLab/RcppTskit/blob/main/RcppTskit/src/RcppTskit.cpp (search for rtsk_table_collection_.
