- Added `rtsk_mutation_table_add_row()` and
`TableCollection$mutation_table_add_row()` to append mutation rows from
\code{R}, mirroring `tsk_mutation_table_add_row()`.
- Added `rtsk_node_table_get_row()` and `TableCollection$node_table_get_row()`
to retrieve node-table rows by 0-based row index.
- Added `rtsk_table_collection_sort()` and `TableCollection$sort()` to sort
table collections with 0-based `edge_start` semantics.
- Added low-level variant iterators
(`rtsk_variant_iterator_init()`/`rtsk_variant_iterator_next()`) and a
user-facing `TreeSequence$variants()` method to iterate over decoded
site-by-site variants from \code{R}, aligned with `tskit` Python API
semantics for `samples`, `isolated_as_missing`, `alleles`, and
`left`/`right` intervals.
- Added `rtsk_treeseq_get_samples()` and `TreeSequence$samples()` to retrieve
sample node IDs from a tree sequence.
