Implement set_row_value method

[martinRenou]

Issue number of the reported bug or feature request: #

Fix #352

Describe your changes

An equivalent to the current set_cell_value method, but for setting entire rows.

Testing performed

Manual Notebook tests + adding a unit test in JS

Additional context

For users, it's more convenient/performant to have this kind of APIs than having to call set_cell_value many times. We may want to implement the equivalent for columns at some point.
