feat: support {equation}, {equation*}, and {split} (#2369)

* Support {equation}, {equation*}, and {split}

* Update screenshots

* Allow {split} at top level

* Move equation column number check to to ParseArray

* Add token to ParseError

* Sharpen parameters passed to parseArray

* Add token information

* Update an {array} spec in screenshotter

* Adjust {array} screenshotter spec

* Make a non-strict error call when {array} argument specifies too few columns.

* Move context checks to a helper function.
