 - Added TableCollection and reticulate Python round-trip helpers:

+- Changed the R API to follow tskit Python API for loading:
   `ts_load()`, `tc_load()`, `TreeSequence$new()`, and `TableCollection$new()`
   now use `skip_tables` and `skip_reference_sequence` logical arguments instead
   of an integer `options` bitmask.
 
 - Removed user-facing `options` from `TreeSequence$dump()`,
   `TreeSequence$dump_tables()`, `TableCollection$dump()`, and
-  `TableCollection$tree_sequence()` in line with the Python API.
-  These methods now call the C++ layer with
-  fixed options matching the Python API.
+  `TableCollection$tree_sequence()` to match R API with the tskit Python API,

-- The bitwise options passed to the C++ functions are now rigorously validated.

   * checking whether package 'RcppTskit' can be installed ... WARNING
   Found the following significant warnings:

+  I have now addressed it by setting CXX_STD = CXX20 in Makevars.in.
+  Note that discussion with upstream devs of tskit indicates that this warning
+  seems to arise from how the build tools have been built for CRAN windows,

+  tweaking the flags, including Windows. See the above checks and
